I see this has been asked a few times in the past, but each thread is usually left with the question "why would anyone want to do that?" I have a use case for you:
I'm re-animating a character for Election Year Knockout using the old one as reference within the same file, and there are a couple of common bones I use for overall composition. When copying what is essentially a list of ordered numbers (the local bone transforms, specifically), it makes sense to me that I should be able own the consequences and paste those numbers onto any bone I please across skeletons, the same way I'm allowed to do so within a skeleton.
This does not work. In previous threads, you mention the keys are pasted into the /previously/ selected bones in the first skeleton.
Perhaps I'm wrong and your copy/paste function relies on the transforms from each parent up the tree, but in the event it's possible I'd love it if you'd take this as a feature request.
