Custom Notification sounds and overrides

I, and I think it's safe to say almost everyone, has certain DMs and servers they ignore. I would love custom notification settings where you can set sounds for when specific servers or DMs are messaged. The sounds could be user uploaded, from a set list, or both. It would be useful because sometimes I'll get a ping while I'm busy and ignore it thinking that it's an announcement from a large community server, but then I'll check later and see it was a friend trying to talk with me, sometimes even about something important. I'd like to be able to set specific sounds for people so I know who/what server it is.

Another very useful feature would be able to set overrides for DND, or have a "mute all" option that allows you to unmute only specific servers and DMs. Sometimes I'll be doing something and I'll want to go DND, but there's certain people/servers that if you're close friends with them, or it's a server you're modding, you'd want to still get a ping from them in case something happens or someone specific is trying to talk to you.
