Controlling with just one MIDI deck issues

HI all,
I wondered if is there a way to auto select deck who is controlled by the physical MIDI deck controller?
Trying to get a lighter config for parties, I’m currently trying Mixtour+CDX6 Midi controller (for wheel control).
Until now, I had to assign buttons to select deck A or B and then control the track in cue to prepare it. But I still have errors (from my part) cause when adding a track to cue, if I forgot to switch deck manually, the wheel still controlling the latest deck (witch is currently playing…)
So I wonder if there is a way to auto select deck when loading a track for cue?
Regards.
