By selecting the track names this will sync playback to host/preview,
the track names just needs to be highlighted to to be seen easily

To select/deselect a track maybe just left click.
Left click + shift for multiple.
Left click + ctrl (or alt) to deselect all.

Another way if the above can't be done, below in the pic the master drag export is on the right giving room for a Mute/Play button for each track, a no brainer to work out.. maybe it could right click like BB to solo a track and ctrl right click to solo another..
