Force fullscreen on second (not primary) monitor?

[Annunakitty]

Eyy, this is a shot in the dark but I'm curious if there's a setting I can throw in the config file that will tell the game to be full screen on my second monitor in my dual monitor setup?  A lot of games will let you drag the windowed-mode window to the other screen and then fullscreen on that one, but that method is not working with this game.  I'd rather not have to change my other monitor to the primary if at all possible, but I didn't see anything about this on a cursory search of the forums so my hopes aren't too high.

Thanks for any and all insight!
