Expression switch mode in midi output settongs

Using mission quad cortex expression. It has a foot switch which can be assigned to expression 1/2
When assigning foot switch there is an option to choose switch or expression ?
In midi output sweeting’s there is just expression 1 and 2 if I want to use the foot switch to toggle a cc it is messing with my other midi gear. Can you expand toggle switch in midi out settings to make use of the expression foot switch in midi. As well as the expression pedal
For example allowing on and off 0-127 values so that you can toggle a control message I think this might require 2 box to input values allowing the foot switch to toggle between ??
