[Suggestion] Feature Suggestion- Different/custom notification sounds for friends

I am at the top of a Discord that has 5000+ people online at any given time. It is part of my IRL job to answer DM's from those people. I really want to be able to tell the difference from a DM from a friend or a stranger when I hear the notification. Sometimes my friends slip through the cracks! Perhaps there could be some options to choose from, or even a way to upload your own notification sounds for friends/strangers? My husband also works for this company and answers DM's. I can never reach him when I want him because he's so desensitized from all the DM's he's gotten from that server. He's trained himself to ignore the DM notification sound when he hears it, so he can answer people's questions later. I want him to know when it's me DM'ing him too! This would really help me, and other influencers out too.
