Multiboby Sheetmetal Flatten/Unfold

I have an cylinder inside of another cylinder, both with a .002 wide slit in them. I want to be able to cut the ends of the cylinders at different angles then be able to flatten or unfold  each of cylinders afterwards.  The issues I have come accross is that when I try to "insert bend' I get an error and this tool can not support multi bodies.

Thanks!
