Separate volume sliders for voice chat and stream

I'm not super familiar with how these boards but I just had this thought and I think it's a good idea:

I was just on a group chat, and watching a stream on that channel. There were moments when I wanted to hear the stream more than the people talking in the channel, but if I lower the overall output volume it also lowers the stream volume. It'd be nice to be able to lower the volume of the people talking in chat while maintaining stream volume. I know that the stream itself has a volume setting, but if I have a moment where I want to turn down everyone rather than deafening, it'd be cool to turn down just the voice participants and not the stream(s) I'm watching.
