I’ve looked for this option several times over the past few years… it’s been so long that I don’t even recall if I’d already added my interest for this feature. This would be so useful for many reasons. Literally having to re-encode files simply to reassign their language so that localized subtitles can automatically be added… or having to go one-by-one to each file in a series is absurd. Both of these are time consuming, and even looking to come up with a programmatic solution to automate a personal fix every time a user comes across another use case where they’d like subtitles for multiple files… that’s basically not even worth the time needed.
Seriously devs, why not prioritize this and knock out a win for years of interests, inquiries, complaints from some long-term customers? Surely this can’t be THAT much work to incorporate a simple button or toggle in the ui, can it?
