Feature idea: automated switch from erg to resistance mode

I have recently switched from a dumb trainer to a smart trainer, an Elite Suito. After trying out all modes, I found out I prefer erg mode for Z2 workouts, warmups and rest intervals, but anything at or above sweet spot I prefer resistance mode.

Switching back and forth on my iPad, especially in an oxygen-depraved state, is finicky and hard. And with the touch interface on the iPad, short cuts are of no use.

So I thought this might be an idea for a feature. What do you all think?

I believe the desktop app allows switching with a single hotkey.

I use my phone and wouldn’t use the feature personally. I use erg for everything including sprints. Tacx Neo.

Like I wrote, I’m on the iPad app and cannot use hotkeys.
