Breaking apart drawing?

So once again I have an assembly that has grown out of control. Hind sight being what it is this assembly should have been broken up into S/A's and put on multiple drawings. Is there a "Best" approach to accomplish this after the fact? Is there a way to create the S/A's and not loose all drawing views, ballooning etc that already exists?

I'm not real crazy about the idea of creating the S/A's and then redrawing everything when this is already done but working with this file is simply painful at the moment.

Thanks,
