Independent media volume controls (News, etc) for cell phones

You can easily and intricately enough adjust your ringer volume in-game by disabling Mouse Control and using the left and right arrows to adjust the percentage.  However, all the Weazel News broadcasts, etc are very loud and I've yet to find a way to control that volume as it isn't tied to your ringtone volume.  I presume this is because it's coming from a YouTubhe source possibly.  It'd be wonderful if we had a volume adjustment of some kind for Weazel News broadcasts, etc.
