Setting multiple notification sounds

I would love to have different notification sounds for different things. 
 
-Direct messages should have a different sound by default than messages in servers.
-Likewise for @ mentions.
These would allow for better ‘attention getting’ if, like me, you have multiple message dings per minute and are doing something full screen.

Even better, it would be fantastic to be able to set custom sounds per server, @ type (you directly, here/everyone, specific roles, etc.), and messages (either dm or in a server) from certain individuals.  This would allow for fine tuning message priority without having to switch to the discord window for every beep.
