Disabling analyzing of fields not present in index template

Can I combine dynamic_templates with index templates? We have defined index templates that apply to indices created with a prefix. For example following index template will create a mapping to any index starting with "te": 

PUT /_template/template_1
{
  "template": "te*",
  "settings": {
    "number_of_shards": 1
  },
  "mappings": {
    "type1": {
      "_source": {
        "enabled": false
      },
      "_all": {
        "enabled": false
      },
      "properties": {
        "host_name": {
          "type": "string",
          "index": "not_analyzed"
        },
        "created_at": {
          "type": "date",
          "format": "EEE MMM dd HH:mm:ss Z YYYY"
        }
      }
    }
  }
}

I also want to combine dynamic_template kind of functionality, so if any new "string" field comes in the data, its analysis gets disabled by default.

Should be able to specify the dynamic mapping in the index template

Example:

 {
      "template": "te*",
      "settings": {
        "number_of_shards": 1
      },
      "mappings": {
        "type1": {
          "_source": {
            "enabled": false
          },
          "_all": {
            "enabled": false
          },
          "properties": {
            "host_name": {
              "type": "string",
              "index": "not_analyzed"
            },
            "created_at": {
              "type": "date",
              "format": "EEE MMM dd HH:mm:ss Z YYYY"
            }
          },
          "dynamic_templates": [

            {
              "strings": {
                "match_mapping_type": "string",
                "mapping": {
                  "type": "string",
                  "index":"not_analyzed"
                }
              }
            }
          ]
        }
      }
    }

The above example would ensure any dynamic "string type" field for type1 would be unanalyzed.
