MIDI Remote Fader/Pot Pickup, when?

Does Steinberg plan to implement this any time soon?

My Launchkey MK3 picks up flawlessly in Studio One (using HUI) and Ableton Live, but does nothing jut jump parameters in Cubase Pro 12.

Even my Oxygen Pro 49 picks up in both of those, but not Cubase Pro. The option in the application appears to do nothing at all.
