Mobile notifications filter?

My guild uses the Rythm bot to play music in their voice chat rooms, and it's a cool feature. But I didn't like all the spam that it produces in the chat, so I've set the chat to block Rythm's messages and that worked great. But almost as bad is when they're using chat to tell it to play songs by using the "!play" command. Sometimes when they're really going at it there will be 30+ posts an hour filled with !play, !skip, !stop, etc... I love being notified when I'm out an about of what's going on in chat, but this doesn't really add anything unless I'm actively in their voice chat. I would love it if you guys could implement a notification filter that would just filter these posts out from being pushed to mobile. With some logic that if any post begins with a "!", just ignore it.
