The number of columns in the folder list is fixed, so currently there is no way to display another field.
'Copy self' folders behave differently when PMail generates the copy in them, and the contents of the 'To:' field are put into the address column. (It's all held in the folder index.)
I have no knowledge about changes that may happen to the folder list and structure, but you could put a request in the wishlist forum.
