Custom notification sounds for channel entry

So I was wondering whether it'd be possible to add a feature where you could give yourself a custom entry sound when entering channels. For example you'd upload a mp3 clip of a maximum of a few seconds, and that would be used instead of the usual bleep noise when you enter a voice channel. This would make it a lot easier to see who's joined the channel, but it could also make discord a lot more fun C: perhaps having this only be a feature when you have discord nitro because it's special?
