Sorry for the delay in responding to this cholla but I’ve been away for a few days.
I’m not sure that that’s possible in the software as the text descriptions you normally see for each audio track describing which is which are added by the studio.
Sometimes they chose not to fill these details in and as all the tracks are the same length and potentially the same format then I don’t think it’s possible to tell which one is which without human intervention.
If they choose not to add descriptions then you’re never 100% sure as to which is which although as you’ve discovered it’s usually the first track that needs to be selected so that’s why it’s the default.
If I’m in any doubt I normally use a software player to determine which track is which as the order the tracks are listed is the same. This is sort of what you’ve been doing with Preview option but will tell you the correct track without you having to listen to them all.
