bVNC Pro can't ssh tunnel to Unix domain sockets

[lack]

bVCN Pro ssh tunneling works great if the remote endpoint is a tcp service, like localhost:5900

However, the wayvnc server I'm using can be configured to listen to a Unix domain socket instead, which is even more secure.

openssh commandline switches support port-forwarding to Unix domain sockets, but the bVNC Pro ssh forwarding dialog doesn't seem to allow this.
