New idea: voicemails for voice channels

How about a feature where before you go afk in a voice channel, you can click a button to "leave a message", so when someone else joins the vc, they can look at your icon and next to where the "muted" button usually is if you're muted, there's some voicemail symbol, and they can click it and hear you say "just gone for a cuppa! be right back". Great for when your friend dropped you a message, "just gimmie a min to finish this work and I'll meet you in vc" and you're waiting on them to turn up but really need to pee and don't want them to turn up while you're gone and wonder where you are, or when you and your mates just finished a game of League and everyone's yelling at once about jungle diff or whatever and everyone's gone afk for a pee or a drink or whatever and you're like, "wait is Ollie coming back on or was that his last game? where's he gone? can anyone remember what he said?" boom, he left a voice message, now everyone can click it and hear him say he's gone to help his sis with homework and to start one without him! How's that for a good idea ;)
