Adding bodies to parts from other parts

Hi all,

I'm trying to see if there is a way to add bodies to an existing part from another part without the "insert part" method.  Originally, I have a part that was created by selecting bodies in an existing part, RMB and "Insert into New Part".  I would like to update that created part by adding a couple extra bodies from the part from which it was orginially created, but I'd like to not have to insert a part, but would like something like "Insert into Existing Part" with the RMB.

I don't think that functionality exists, but please correct me if I'm wrong.

Thanks,

Mike
