Audio Control for individual Notifications

In the last days of using the TS5 beta I noticed that I have the Problem of reliably hear my Chat Notifications. I looked in the Settings for the Notifications and saw that you can set a Volume for all Notifications. My Problem is that if I’m not focusing on Teamspeak I tend to blend out the (in my eyes) silent “You received a message” Notification and if I turn up the overall Notification Volume thinks like moved to your Channel are really loud. I know that pining my messages in the Settings Tab would make it possible to only hear the message Notification but as soon as I unmute myself the loud “User joined your Channel” starts again, and I need to turn the Volume down. So my Idea would be to add a independent Sound slider for the Notifications under the advanced Tabs of each Notification to give the user a more advanced control over the Notifications.
