Though I also wish they'd let me set better defaults. They let you give a list of languages you prefer, but that's too simplistic. E.g. I'd prefer to always get original audio, but subtitles matching the audio in a handful of languages I know well enough to follow if I can read but not only by audio, and falling back to English.
Instead you need to check for each series what is available, or set it broad and change it per program accordingly.
