Ability to set description to whole entity

It seems there is no way to set global description for the whole Entity. If use grape-swagger-entity, it takes entity definition outside from resource, which I think is incorrect.

{  
   "definitions":{  
      "User":{  
         "type":"object",
         "properties":{  
            "username":{  
               "type":"string"
            }
         },
         "required":[  
            "username"
         ],
         "description":"Create a token from email/password pair"
      }
   }
}

This description seems being used nowhere, but it can be used as description on resource response section, when you set desc "Retrieve information about the signed user", entity: Entities::User

"responses":{"200":{"description":"User entity","schema":{"$ref":"#/definitions/User"}}

instead of

"responses":{"200":{"description":"Retrieve information about the signed user","schema":{"$ref":"#/definitions/User"}}

Start by tracing how grape-swagger-entity handles entity definitions and how the desc entry point builds resource response descriptions. Confirm whether the entity-level description should populate the response description instead of the resource description, then add coverage for the shown User response shape.
