Sorry, this is an issue that only exists in your head. It doesn’t matter in real life if you put the fader on exactly 0dB or +0.2dB or -0.3dB.
Such dent would have to be programmable. I wouldn’t like to have those dents at the 0dB input/output fader line when in GEQ fader flip. Also I have these situations too, where I need to pull back some outputs for a short time a place them back to were they where, but I never had the feeling “I need dents”. For this problem I would rather prefer other solutions. One would be an “auto scene update when recalling another scene” updating the last used scene if you recall a new scene, so you have stored your last settings. Another would be a “undo scene change buffer” where you can go back to the last settings before recalling a scene.
