Mute sound tabs problem

First of all great browser, has potential and its fast
But the problem is when you have many tabs with sounds and you just want to mute all except one it dosent work. It seems you can only mute all tabs and not one by one. Any thoughts?

Version im using now: Version 0.66.99 Chromium: 75.0.3770.100 (Official Build) (64-bit)
