I usually drag the tracks from multi-output rack instruments so they’re below their respective midi track. This means they’re all visible quite easily next to each other, downside is that it takes up quite a bit of space on-screen… I have some macros programmed for showing/hiding these ‘extra’ tracks when I’m just working on midi or just working on the audio output.
[Note, there’s a quick way of bringing them together too, by selecting both tracks then moving the midi track up one track then back down - this operation moves all selected track to be together.]
