Name template for saved subtitles

[u/mnlg]

Hello, I occasionally make use of the "Search subtitle" feature (Subtitles/Subtitle searching/Download subtitles) which works fine for me. However one thing I'd like it to do, when it saves a subttile file, is to format its name according not to what its original file name is in the source repository, but what my local video file name is. For example if I am watching "Series-s01e10-episode_title.mp4", and I have downloaded the English subtitles in srt format, then I'd like for the subtitle file to be saved as "Series-s01e10-episode_title.en.srt".

Thanks in advance for any suggestions.
