Join call sound

Hallo everyone just up vote this so could become a reality :D. we would like an application to Discord, where i can make my friends that join my call/server that i'm in, make a different sound like "And his name is John Cena, dumdedadum" so i know which of my friends just joined. This would be legendary if its implemented. and would probably increace the net worth by 200% and meme content by 500%. All in all a "win win."
