How to create the universal Wah

MISSION::

I am using a Boss EV 30 pedal in omniport 3 of my MC8 Pro - to create a wah effect, on my Source Audio EQ2 pedal

Whichever current EQ2 preset is in use - i have targeted EQ band 4 to sweep the frequency.
At heel down i want to RESET the pedal back to the original EQ PRESET , by sending a PC Message to the EQ2 pedal.

I have several guitars - so I use a Counter “Current Guitar” as a global pointer - which is set by the MC8 Pro to the appropriate EQ2 PC number ehen changing guitars.

PROBLEM

I cannot access the counter message types from the expression pedal expression 3 preset. I only see send pc number on heel down. Can you add the Counter message type to the expression list.

Is there another way to do this?

Would this message do the job ?
