Set audio priority of selected 'Now Playing' channel higher than all other audio

[DSheirer]

When the user selects a row in the 'Now Playing' table, override the audio priority of all audio calls for that channel so that the channel's audio will override the audio panel call and be played.

Just wondering how this is coming. I just started using sdrtrunk, which works great, but in a busy trunk system, it can be quite difficult to isolate particular calls of interest. For example, a call comes in on one talkgroup that I decide I want to follow, before a response comes in, three other talkgroups start up activity, which buries the original talkgroup unless I had previously marked it for priority (I didn't).

If there were functions equivalent to mute/solo, like in a Digital Audio Workstation, or even the ability to temporarily supercede priorities, it would make it much easier to temporarily "zoom in" on relevant information or otherwise crop out noise.

According to the audio panel wiki page, it looks like there's some capability for this: "You can override all call priorities defined in the system when you select an individual decoding channel. Any audio produced from a selected channel is routed with the highest priority for playback." Is this currently implemented? It doesn't seem to work in v0.5.0-alpha6, or else I just don't know how to "select" a channel.
