Does Custom Resource State Metrics support deep nested objects?

[pbxqdown]

We have a k8s object as follows.

status:
    resourceCount:
      tenantA:
        hostGroupA:
          example.com/type1: 2
          example.com/type2: 2
          example.com/type3: 20

We would like to generate a metrics like resourceCount{tenant=tenantA, hostGroup=hostGroupA, resourceType=type2} 2.
Initially I tried to use labelFromKey, but it seems only supports one level of nesting. I have to statically specify path, and in the last level use labelFromKey to generate metrics by resourceType.

metrics:
            - name: resourceCount
              each:
                type: Gauge
                gauge:
                  path: [status, resourceCount, tenantA, hostGroupA]
                  labelFromKey: resourceType

Wondering whether we can use labelFromKey for nested objects.
