Ext TRS switch for press button?

Is there a way to use the ext jack with a trs switch to control the press button? Maybe a momentary switch so you could do the long presses. This would make the pedal a lot easier to control on the floor

For the push button (small button)? Or the footswitches?

The small push button, sorry.

The push button is not mappable to the CV / expression input. You can map any specific parameter(s) as well as the Touch footswitch.
