Yes, you could use a dynamic template for that. Dynamic templates allow you to change how fields get mapped dynamically. In your case, you could use that to enable store on all dynamically mapped keyword multifields:

PUT my_index
{
  "mappings": {
    "dynamic_templates": [
      {
        "strings": {
          "match_mapping_type": "string",
          "mapping": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256,
                "store": true
              }
            }
          }
        }
      }
    ]
  }
}
