RB Prepare Mode on DDJ-RX

I use the XDJ-RX. Unfortunately the Midi mode does not work in Prepare mode.
It can not be true that you can not use the controller Hardware Keys for track preparing ?
In any software like Traktor or Serato can I use the hardware keys on the controller to play, jog wheel or hot cues.
It would be bad if I have got a controller for more than 1,000 € and for track preparation I have to use the mice :(
