Not enough layers?

I’m making a game where missiles are created using the duplicateMovieClip thing and I’ve used it a lot before, but i never noticed that there is a limit to the number of layers, around 256, I think. The problem is that i have a bunch of sprites in my games and each of them move(i.e. fire,smoke,shrapnel from rockets,etc) so is there a way to group a large amount of movie clips so that they’re on one layer, without putting them into another movieclip?
If u want look at a part of my game, well two parts.
