Path as an array

I have an object similar to this:

```json
{
"1": [
{"a": "valueA", "b": "valueB"},
{"a": "valueC", "b": "valueD"},
],
"2": [
{"a": "valueE", "b": "valueF"},
{"a": "valueG", "b": "valueH"},
]
}
```

I want to apply a transformation across all arrays of each key in the object in a similar manner. Using `path`, I can pick up on each key individually and transform as needed but I am having issues applying the same across all other keys in the object.

Is there a way to provide an array of paths like so:
`path: ["1", "2"]`

Or is there another way to do this?
