Breaking up Complex Polys

[Yoda]

I had to copy a LARGE Poly using 'copy poly to brush'. Now that I have copied it, I want to break it apart and make a few adjustments. Can this be done to the 'copy'?

What you can do is bring that copy into a building box (just a big subtracted area). You can then mutilate it there. Then make the entire thing 1 brush by intersecting.
