In the `docker-compose` config for one of my stacks I’ve got this:

```auto
SYSLOG_HOSTNAME: {{ index .Container.Config.Labels "io.rancher.container.name" }}

```

and then in the logs this is shown with a hostname as `ipsec-ipsec-router-4`, for example.  
Is it possible to add the environment name to the syslog\_hostname value? So that it goes like `development-ipsec-ipsec-router-4` for example?
