Cut List question

Hello,

I created a multi-body part, with some of the bodies welded together and some to be bolted.  After it was finished I saved out the bodies that would be welded together as a seperate part.  Now when I open this part there isn't a cut list.  I added a new body and then the cut list was there.  I deleted the new body and the cut list stayed, but is there a better way than this workaround?  It's probably something simple, but I'm new to saving bodies as parts and I can't figure it out.
