Any good ideas/ways to quickly/easily swap between Crossfire enabled/disabled?

I have a monitor hooked up to each 6850 I have installed, however when I enable crossfire (to run single-box or other 3-d games), the 2nd monitor goes dark.

Is there a good solution to this? Or do I have to just manually hook the 2nd monitor up to the 1st video card and back depending on how I want to play?
