Syslog and Docker + adding tags

Hi,

I have on my Nomad docker config something like this:

          "logging": {
            "type": "syslog",
            "config": {
              "syslog-address": "unixgram:///dev/log",
              "tag": "docker/{{.Name}}",
            }
          },
          "extra_labels": [
            "job_name",
            "task_group_name",
            "task_name",
            "namespace",
            "node_name"
          ]
        }

is it possible, to add some of the extra_labels to the “tag”, like namespace and job_name? ?
