Arthur, if you change the settings for the screen, it would work. I'm assuming you're wanting something other than the blue/green/red background for odd, even, and break rounds?
If you go to the layout tab, and click Global Properties, you'll have the ability to change universal settings for odd, even, break, next odd/even rounds, and then some. Does this cover what you're looking to do, or do you need something else?
