I don't think this exists at all in the plugin, but we'd be happy to accept any pull requests that add it.

We'd like a feature like that :-)

Currently we work around it by passing build arguments that are then used as the values of LABEL directives in the Dockerfile. (But there is a bug with build arguments containing spaces: #286)
