Open apllication on already opened terminator

view story

http://crunchbang.org – Hi guys, can I ask for your help?I RTFM of Terminator, but I can't find a solution.I would like to know if it is possibile to set a command in my openbox-menu that opens an application to an already opened Terminator.Example: I am listening to ncmpcpp and I would like to check my emails. I can manually split terminator and launch Mutt...but it would be cool to rightclick on the desktop and press "Mutt" in the openbox-menu and see Terminator automatically split and launch Mutt, instead of open a new Terminator window.It is possible or is it fantasy?Thanks for your help!!!
