How do I attend two meetings and also adjust the individual volumes?

[0ak1and]

I can easily open up two concurrent webinars at the same time. However, there isn't any control to silence one of the meetings. So, I can't switch listening between the two since any volume controls affect both meetings equally.

Is there any way I can adjust the volume of individual meetings? For example, I want to open up two meetings and be able to switch my listening focus between the two.
