It just crossed my mind that I’ve left a pretty related wish:
it was changed during the discussion to keep it simple, but originally, I proposed the feature to bind filter sweeps to shift+mute combo with any duration set in menu, per track, in seconds. you guys @here, feel free to make a new wish like «ability to bind custom duration filter sweeps to shift+mute combo» or «mapping different sweeping effects/knobs to shift+mute combo». back then I postponed it to see if the original wish will be approved at all. you may also want to make a reference to this and that thread.
a huge plus in this approach is that it’s free from the sequencer grid and can be a lot longer without stepping.
