Endpoint to retrieve tags under a category with descriptions

I need a way to retrieve tags under a given category with tag descriptions (which are actually used across the UI as the title of the given tag). For now I have this request, that returns me with the tags under a category:

# curl -XGET http://admin:smartvm@localhost:3000/api/categories/1\?expand\=tags | jq
{
  "href": "http://localhost:3000/api/categories/1",
  "id": "1",
  "description": "Location",
  "icon": null,
  "read_only": false,
  "syntax": "string",
  "single_value": true,
  "example_text": "The geographic location of the resource, such as New York, Chicago, or London.",
  "tag_id": "3",
  "parent_id": null,
  "show": true,
  "default": true,
  "perf_by_tag": null,
  "name": "location",
  "tags": [
    {
      "href": "http://localhost:3000/api/categories/1/tags/4",
      "id": "4",
      "name": "/managed/location/ny"
    },
    {
      "href": "http://localhost:3000/api/categories/1/tags/5",
      "id": "5",
      "name": "/managed/location/chicago"
    },
    {
      "href": "http://localhost:3000/api/categories/1/tags/6",
      "id": "6",
      "name": "/managed/location/london"
    },
    {
      "href": "http://localhost:3000/api/categories/1/tags/7",
      "id": "7",
      "name": "/managed/location/paris"
    }
  ],
  "actions": [
    {
      "name": "edit",
      "method": "post",
      "href": "http://localhost:3000/api/categories/1"
    },
    {
      "name": "delete",
      "method": "post",
      "href": "http://localhost:3000/api/categories/1"
    },
    {
      "name": "delete",
      "method": "delete",
      "href": "http://localhost:3000/api/categories/1"
    }
  ]
}

But the description is not part of the expanded tags, however, I found a solution to fire a second request that returns me the descriptions as well:

# curl -XPOST http://admin:smartvm@localhost:3000/api/tags/\?attributes\=categorization -d '{ "action": "query", "resources": [ { "id": 4 }, { "id": 5 } ]  }'

{
  "results": [
    {
      "href": "http://localhost:3000/api/tags/4",
      "id": "4",
      "name": "/managed/location/ny",
      "categorization": {
        "name": "ny",
        "description": "New York",
        "category": {
          "name": "location",
          "description": "Location"
        },
        "display_name": "Location: New York"
      },
      "actions": [
        {
          "name": "edit",
          "method": "post",
          "href": "http://localhost:3000/api/tags/4"
        },
        {
          "name": "delete",
          "method": "post",
          "href": "http://localhost:3000/api/tags/4"
        },
        {
          "name": "delete",
          "method": "delete",
          "href": "http://localhost:3000/api/tags/4"
        }
      ]
    },
    {
      "href": "http://localhost:3000/api/tags/5",
      "id": "5",
      "name": "/managed/location/chicago",
      "categorization": {
        "name": "chicago",
        "description": "Chicago",
        "category": {
          "name": "location",
          "description": "Location"
        },
        "display_name": "Location: Chicago"
      },
      "actions": [
        {
          "name": "edit",
          "method": "post",
          "href": "http://localhost:3000/api/tags/5"
        },
        {
          "name": "delete",
          "method": "post",
          "href": "http://localhost:3000/api/tags/5"
        },
        {
          "name": "delete",
          "method": "delete",
          "href": "http://localhost:3000/api/tags/5"
        }
      ]
    }
  ]
}

However, the request building is a little messy as I have to specify all the tag IDs one by one and then merge the result. So my question: is there a way to do this in a single request, by specifying a magic attribute that adds the description field to the expanded tags?

Start with the category endpoint's expanded tags response and the tag categorization query shown in the issue. Determine whether the API supports a single expansion or attribute request, then verify that one category request returns each tag's description without manually listing IDs or merging results.
