Create secondary index on attribute inside dynamic object attribute

Hi,

I have a sample doc like:

 "reqProcs": {
    "12345": {
      "UID": "abcd123",
      "refPhy": {
        "id": {
          "use": 3001,
          "type": "STARTER1",
          "system": "STARTER1",
          "value": "468268321"
        },
        "name": {
          "use": 3001,
          "family": "lname1",
          "given": "fname1",
          "other": [],
          "prefix": "",
          "suffix": ""
        }
       } 
      }
    "78901": {
      "UID": "abcd456",
      "refPhy": {
        "id": {
          "use": 3001,
          "type": "STARTER2",
          "system": "STARTER2",
          "value": "0123456"
        },
        "name": {
          "use": 3001,
          "family": "lname2",
          "given": "fname2",
          "other": [],
          "prefix": "",
          "suffix": ""
        }
       } 
      }
    }

Is it possible to create a secondary index on reqProcs..refPhy.name? id is dynamic value.

Thanks,

Matt
