Can a preset toggle another preset from 2 to 1 but not 1 to 2?

I have a preset that is in toggle mode as a wet dry (c) and a preset that is a kill switch to revert back to 100% dry (e). Can I set it up to where if I hit (e) it will toggle (c) if it is in position 2 but not toggle (c) if it is in position one?

On the Set Toggle function, try using either Engage or Disengage, one of those should work.
