Awesome question! Gimme a second for my brain to rack through the archive's....
Okay so I believe I do remember seeing this somewhere, it may be a feature of one of the many FPSC game package makers (such as GameStarter or FPSC V-Packer), but I'm not too sure. I am fairly certain this can be done some way or another though, perhaps take a look at GUI-X9: http://forum.thegamecreators.com/?m=forum_view&t=190129&b=21 (Also there is a free version that comes with the recent versions of FPSC, look in your FPS Creator root folder for it.)
Have a look around and come back with a reply if you find something, I'd be interested to know
