Save subtitles filenames chosen for video

I went through several series selecting subtitle files that were the best for the episodes but the system didn’t save the preferred filename with the episode leaving the horrible task of having to reselect them again. If someone turns the subtitles off that selection no longer exists and must be redone for every episode where they were turned off and maybe there’s another way the su titles get dropped too?

Please save the selected subtitle file last chosen with the associated episode or lets us mark them and lock them in so no accidental changes are made.

This is a mess having to redo this work.

I assume your suggestion is aiming at on-demand (online) subtitles which you searched before watching a video? Or is this about manually selected subtitle tracks on local media?
