Include/Exclude for cardinality aggregation

Elastic Stack Elasticsearch
1

I have a terms aggregation with an IncludeExclude filter:

{
  "size": 0,
  "query": {
    ...
  },
 "aggregations": {
    "facets": {
      "terms": {
        "field": "type_id",
        "size": 20,
        "order": [
          {
            "_count": "desc"
          },
          {
            "_key": "asc"
          }
        ],
        "include": "PARENT$.*",
        "exclude": ".+__\\*"
      }
    }
}

This will return me the top 20 facets for field type_id. I also want to know the total number of unique terms for this facet, so I want to add another aggregate:

 "total": {
      "cardinality": {
        "field": "type_id"
      }
    }

but I can't filter this total by include/exclude, so the count doesn't match with the terms aggregate above. Is there an efficient way to achieve this?
