**Versions** (relevant - OpenSearch/Dashboard/Server OS/Browser):  
OpenSearch Version: 2.5.0  
OpenSearch Java Version: 2.4.0

**Describe the issue** :  
I am trying to create a dynamic template for a new index, and would like to use `{dynamic_type}` template variable in the following template like so:

```auto
{
   "mappings": {
      "dynamic_templates": [
         {
            "strict_mappings": {
               "mapping": {
                  "type": "{dynamic_type}",
                  "dynamic":"strict"
               },
               "match":"*"
            }
         }
      ]
   }
}

```

But, it looks like that the [Property class](https://github.com/opensearch-project/opensearch-java/blob/v2.4.0/java-client/src/main/java/org/opensearch/client/opensearch/_types/mapping/Property.java) does not support adding a template variable. I would like this strict mapping for all the fields in an index. Is there any workaround for this or when will this be supported? Thank you!
