In elastic we have copy_to parameter for copying the fields. Is there any way to replicate the same in mongodb while indexing?

{
        "global_string_mv": {
          "match_mapping_type": "string",
          "match": "global*_string_mv", 
          "mapping": {
            "type": "text",
        "copy_to": "global_fields_string_mv",
            "fields": {
          "text_en": {
            "type": "text",
            "analyzer": "text_en_index",
            "search_analyzer": "text_en_query"
          },
          "text_en_shingle": {
            "type": "text",
            "analyzer": "text_shingle_en_index",
            "search_analyzer": "text_shingle_en_query"
          },
           "keyword": {
            "type": "keyword"
            }
        }
          }
        }
      },
