AFAIK there’s only per season, if not I assume it would be something you could change in the data manager but you can’t.
Looking at the exporting CSVs, I don’t see it anywhere. So I don’t know whether this is internally saved per episode or per season in the database. That would be a question for @brandon with probably the added request to include the subtitles status in the CSV export?
If you want, I can edit Add custom tags, custom lists to CSV dump information PR to include that for a possible future update.
