Bind mount volumes with web UI

I understand how to tell my cluster to bind-mount a volume when running CLI. Let’s take nginx-proxy for example.
When running the CLI, $ docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock zedtux/nginx-proxy, I understand the host will mount /tmp/docker.sock from container to /var/run/docker.sock. More general, there is something like path/in/host:path/in/container. But I have no idea how to do it with web UI. I guess I must use Volumes > add volumes > Bind-mount a directory from the node, but there after I don’t know how to field the various fields.

Thank you for help.

I know this thread is very old, but did you ever find out how to do this within the UI?
