Maybe strictly refer to the DCP track labels in the audio matrix - that way, whenever these labels change, they are referenced by the audio track detection. At some point e.g. one track could become ATMOS sync track, etc., 15 and 16 for now could be left alone, or, following that scheme, be simply referenced by their number, e.g. '-15', '-16'. At some point, the DCP audio track number selection or DCNC selection could automatically change the audio matrix track labels, and then the automatic track routing could also follow automatically. VI and VI-N should be treated equally (officially, I think it is now VI-N). And of course, all case insensitive.

Maybe you can also add automatic reel detection based on the number immediately preceding the hypen, e.g.

xxx1-LFE, xxx2-LFE

That would make it very easy to import a large bunch of reel and track split audio files and assign them automatically in order and routing. A 'simple' project with 6 reels and 5.1 sound would need manual adjustments of 36 items, which is quite prone to errors and frustration.
Also, add this feature to the manual. I know, not many users read manuals, but then, we can save time by pinpointing them to that section whenever the question comes up ;-)
