Are there any user mappings available

Would be great to have the option to map user and group, commonly used in linuxserver's images, PGID and PUID. Are any of these supported?

Ping @sgoetsch may have an idea.

Currently the docker container runs as www-data owner and www-data group, so I needed to set the owner of my local folder volume to this user to solve the write permissions issue. There are probably other ways about it too, but I find the linuxserver mappings such an elegant solution.
