Lengthy Notification Prefences

So I am a member of a community Discord of sorts and went in to filter out which channels I'd like to receive notifications on at all on my phone. I can go one-by-one through the channels to mark for muting, but it's a lengthy process and I have to reselect each channel each time to toggle it on. Would be nicer if the UI let me bounce back and forth from the channel list to the mute toggle without being kicked to the main/primary panel after confirming. Or could let me do a negative selection, where I can setup a server mute while allowing desired notifications from just a small subset of channels. I can do this easier on the desktop app, but I've been needing to use my phone (Android) more often as of late.

Thank you,
