How do you assign program change = bypass

via MIDI from one factor pedal to another?  i wish to control my PF and TF with an aux switch throughout my show from one pedal.  can i make a bank = bypass?  So , for example, I use PF on 1 song and TF on the next song and both on a third song, i simply want to bank up thru the show, but some songs 1 or the other pedal need to be bypassed.
