Volume/Wah

I would love to have the ability to set a wah block as a volume/wah so when the wah is bypassed the expression pedal becomes a volume pedal. I do this now with two separate blocks, but sometimes it’s glitchy and turns on the wah and turns off the volume when I change scenes. The nice thing about using two blocks in this way is the vol and wah can be located at different points in the signal chain. It almost could be thought of as a side chain feature. When x block is bypasses y block is active. It’s essentially toggling two different effects which works fine with the footswitches but seems glitchy when using an expression pedal footswitch….
