Can the index's roll alias be set dynamically？

Elastic Stack Elasticsearch

I use filebeat to add fields to dynamically generate indexes.

index => "%{[service]}-%{+YYYY.MM.dd}"

I configure the following index template to match the generated index

{
  "index_templates" : [
    {
      "name" : "pre-games",
      "index_template" : {
        "index_patterns" : [
          "*_room_pre*"
        ],
        "composed_of" : [
          "games-mappings",
          "pre-games-settings"
        ],
        "priority" : 112,
        "version" : 1
      }
    }
  ]
}

{
  "component_templates" : [
    {
      "name" : "pre-games-settings",
      "component_template" : {
        "template" : {
          "settings" : {
            "index" : {
              "lifecycle" : {
                "name" : "pre",
                "rollover_alias" : "*_room_pre*"
              },
              "routing" : {
                "allocation" : {
                  "require" : {
                    "box_type" : "hot"
                  }
                }
              },
              "number_of_shards" : "3",
              "number_of_replicas" : "1"
            }
          }
        },
        "version" : 1
      }
    }
  ]
}

When I configured the index lifecycle policy, I encountered a problem:
Normally, an index corresponds to an alias, which should be at the beginning of the index name. But my index template generates index names of different businesses, such as mysql_ room_ pre-2020-04-28； tomcat_ room_ pre-2020-04-28。 If every business needs to generate an index template, then I

I've tried the following method to match index names of different businesses, but it doesn't work

"rollover_alias" : "*_room_pre*"

AFAIK that is not currently supported with ILM, it's something that is being looked at.

OK, thank you
