Subtitles language priority on downloading playlists

Hello, I would like to suggest ideas for downloading subtitles.

1 - To be able to download multiple subtitles for one video (either in separate files or in a .mkv) would be great.

2 - To be able to set the language priority(ies) for the subtitles on downloading playlists (for example take the French subtitles if it's available, the English subtitles if it's not) would be great.

3 - To be able to preset these parameters in the 4k Video Downloader intelligent mode would be awesome.

Thanks for reading!
