Please incorporate the ability to rearrange decks in the interface

When using 2 physical CDJs and 2 virtual decks, it would be really helpful if we could re-arrange the decks within Rekordbox's interface.  

Currently I am using channels 2,3 for CDJs and Virtual Decks for channels 1,2 on a 900NXS2.   It looks confusing on the screen in performance mode because decks 2,3 are diagonal from each other on screen.   If we could re-arrange the way the decks appear on screen that would be really helpful
