Help! Path needs to include object "key" value.

[tswallen]

Hey there! I really love this library so far!

See my problem here.

tl;dr: see my data sample below. If I get the "path" for "Do you find this question helpful?" I will get [x].fieldGroup[x].fieldGroup[x].templateOptions.label but as you will see, these "fieldGroups" have "key" values. So in this case I am wanting to return zero.feedback.a.templateOptions.label instead, any idea how I can add this "key" to the path?

[
  {
    "key": "zero",
    "fieldGroup": [
      {
        "key": "a",
        "templateOptions": {
          "label": "Do you own a car?"
        }
      },
      {
        "key": "feedback",
        "fieldGroup": [
          {
            "key": "a",
            "templateOptions": {
              "label": "Do you find this question helpful?"
            }
          }
        ]
      },
    ]
  },
  {
    "key": "feedbackConsent",
    "templateOptions": {
      "label": "Do you agree to provide feedback?"
    }
  }
]
