### Problem Description

I've run into an issue recently with a playlist I want to sort in a custom way, but doing so interferes with my other playlists, which I need to be sorted by recently added.

### Proposed Solution

I would like to ask if it's possible to remember the chosen sort order per playlist.

### Alternatives Considered

The only solution I've got at the moment is to manually readd all the videos to the first playlist in the reverse order of the one I want them to be in, which is not ideal and I can imagine being even less so for people with large music playlists who also like having a (reverse-)chronological watch later list, for instance.
