I completely agree on this. Being a Stage user the hardware based selection knob is not an issue since that is controlled by a button. As for the other units I am sure this could be worked around with a software change that is only in place while connected to the rig manager, disabling the hardware knob and returning it to its selected function when not connected to RM. Could even have the Kemper screen display that it is a mode controlled by the RM.
I would be 100 % on board with this kind of feature however it could be implemented,
