Speed ++ button?

Sometimes its kinda annoying to wait the creeps come on survival if we all killed them already, would be nice if we could speed it up. this could work as a hardness level adjuster placeholder as well
to make it work, it would have to be voted... if 3/4 or 2/3 or 2/2 wants make it faster, then it would go faster.
