Just double checking, you know not clicking any makes it default all options?
I could see you being more annoyed if you thought you had to click all the maps every time or something.
If you're clicking every map but one or two, maybe you might want to consider just not clicking any and dealing with seeing the matches that are on maps you don't like.
But if lack doesn't think this is a big deal or hard to do I'd like to see it implemented, just saying...
