Fairlight audio output from timeline to another timeline

I have a "master audio mix" timeline which gets put into tracks in numerous other timelines, but I'm not getting the mix output (from another bus) on those timelines.
I can patch the mix output to various outputs on the PC, but I see no way of patching the output bus to the "output" of the timeline - in fact, the Fairlight page seems to have no such thing as an "output".
Studio mixing desks have been part of my entire working life, and I'm really struggling here.
One other semi-related question is how can I lock the track heights and mixer positions in Fairlight, because every time I go back to the Fairlight page, the track heights are shrunk and the mixer has slid off to the right. So, every time I go back there (which at the moment is very often) I have to resize the tracks and fiddle with the mixer to get it back. I thought saving the workspace might lock that, but it doesn't.
And the legend on the left of the mixer is only showing the last letters.
Thanks
