Footswitches Send Exp Control - Feature Request

It would be great to be able to also use the footswitches to send expression control. The RJM Mastermind controller has this option and it is a great way to get more expression without adding several extra expression pedals.

For example the G and H buttons could toggle on and off sends to the DDL or feedback % on the DLL on the fly. Many, many things open up with this option.
