Solr json facet query, unique for particular values

I have following query , For the two company ids, I would also like to get the unique rows (unique_internal_plays and unique_external_plays). Is that possible ?

{
    "facet":{
        "unique_viewers" : "unique(uuid)",
        "internal_plays": {
            "type": "query",
            "q": "company:100"
        },
        "external_plays": {
            "type": "query",
            "q": "-company:100"
        },
       "unique_internal_plays": {
            "type": "query",
            "q": "company:100"
        },
        "unique_external_plays": {
            "type": "query",
            "q": "-company:100"
        }

    }
}

For any facet in the JSON Facet API you can further divide the given facet into nested facets. If you combine this with a stats facet (an aggregate facet), you can get the unique count for a field in that specific bucket:

"internal_plays": {
  "type": "query", 
  "q": "company:100", 
  "facet": {
    "unique_viewers": "unique(uuid)"
  }
}

This will create a nested facet under the facet query, effectively giving you a way to further pivot/run statistics across the set for the matching documents.
