I had an idea for tech lab items, where we can trade pieces with allies when we have two or more of the same piece but are missing a piece.

For example, for the skull watch, I have 12 of one piece, 28 of another, and 0 of the 3rd piece. Same thing with the medallion and stolen paintings...

I just got my second tail piece of the Apache helicopter and have no other pieces for it yet. It would be nice if I could trade that second tail to someone for a missing piece.
