xdj-xz back to back laptop and usb user

When using usb drive on one side of xz and laptop on the other b2b, the rekordbox dj laptop user using the left hand side cannot access deck 3 via short cut menu, please can this be added?

Also it would be helpful in a 3 way b2b session, which I do a lot, that the rekordbox dj laptop user could use decks 3 and 4, while usbs 1 and 2 could be used for decks 1 and 2...thoughts?

Maybe some of this will be fixed with the firmware update that adds the double tap of shift to toggle decks?
