Frame generator Sub-assembly

If you add an end cap, it  would be nice to be able to include the end cap in the demotion process to make the sub-assembly.

Without End CapWith End Cap

I have the same problem. I work a lot with frame generator and many times I would like do this.

Additionaly it should be the opportunity, during creating new end cap or profile,to choose assembly with I want to put it in (main assembly or sub-assembly). It would be great!!!
