Easy Way to Call Up EQ PRESETS On iPhone?

I have my receiver driving indoor speakers and a set of outdoor speakers via zone 2 (never at the same time). I’d like to use a different EQ PRESET for the outdoor speakers. Is there any convenient way to switch between EQ PRESET settings on an iPhone? I can’t seem to find any way to do this. Running back to the Roon appl on my Mac to do this is sub-optimal at best.
