Is there any way to disable the map pack while playing split-screen?

I want to get the crimson map pack, but after playing it at a friends split-screen, I noticed that the frame rate on the new maps is absolutely atrocious, and makes the maps unplayable. I play halo with my brother split-screen all the time, and I don't want the maps showing up in matchmaking while playing split-screen. Any way to disable it for split-screen, then re-enable it for when I play solo?
