Copying player to other rosters

Is it possible with REDitor copy player from one rosters to other rosters with his all the attributes, signature, etc.? How?

Well I think you can copy it and paste it but your best luck is to enter it 1 by 1 in an empty space

An easier way is changing the player's PlType to 5, uploading him to 2K Share and then downloading him. You can change the PlType back to 4 after you get it in the new roster.
