Change scene or preset via foot switch?

[luke]

In a song of ours I have to go quickly from one sound to a totally different sound including a wah.

I was wondering if there is a way to just step on my SP-1 to both engage the wah and change scene (or preset) without altering all my presets that also have wah.

Now I change presets and then go to the wah, the two step process is making me miss the beginning of the line I play.

The global setting for an external switch/pedal can be overridden per preset. Here you could configure any two scene select CC values for switch on/off states. See manual section 12.1.7 for details, or 12.1.9 if using XP port for switch.
