[X2Go-User] How to start a specific program from the client command line?

[Chris Green]

I have been using x2go for a while now to run a couple of desktop
programs on my laptop, I also use it to run the whole of the desktop's
xfce session sometimes.  It's excellent, thank you all.

I currently have an icon in my panel which runs the following:-

    x2goclient --session=<session name>

This brings up the x2go client GUI with the appropriate session loaded
and asks for my password. 

Being a command line junkie I'd quite like to bypass the GUI if I can,
so is there any way to get x2go[client] to ask for the password on the
command line and go on to run the session?

Alternatively can I get x2go to use ssh's ControlMaster setting as I
nearly always have an ssh session running to my desktop so further ssh
connections don't ask for my password again.
