Edit patterned parts individually?

Hello all,

I'm making an assembly with similar, but not identical parts. I used Linear Component to create a pattern.

However, I now need these parts to be identical no more - they have to be cut with Assembly Features -> Simple Cut or something similar. Problem is that I need to Propagate to Parts, and that makes them identical.

Please open my uploaded assembly. In Top view, a line is visible. I need to cut all these patterned parts along that line. If you unsuppress the Cut-Extrude feature, you'll see that my idea doesn't work.

What would be your solution? I really want to use pattern, because it saves a lot of time, and allows modifications.
