Ability to separate discord audio from system/game audio

Hi guys! I'd like to make a feature suggestion to the discord developers and I'm sure you want this feature too! I recently came to pc from console and one thing we had on console was the ability to turn down the audio from party or voice chat separately to the game audio or system audio, this is a great feature to have if you trying to listen to those quiet footsteps or magazine reloads in fps, or your playing an mmorpgs and someone's yelling commands and it's utter chaos but you don't want to leave, I think this feature is much needed and will be widely appreciated if it is added in a user friendly way and maybe with a really advanced and customisable way, down below are what I would like to see and I'm sure many of you guys too. Ability to bind discord master volume or discord chat volumes to a keyboard key or macro key. Ability to bind master discord volume or discord chat volume to an external headset volume wheel if possible. If there are any more features like this please reply to the post and hopefully I see it to be able to update it, THANKS FOR YOUR SUPPORT TO DISCORD!
