[FEATURE] Playlist Prefix

[djarbz]

Is your feature request related to a problem? Please describe.
The auto generated playlists get sorted alphabetically and I would rather group them together.

Describe the solution you'd like
I would like an option to specify a prefix for generated playlists.

Describe alternatives you've considered
Manually renaming them, which can be a chore to keep up on.

Additional context
I'm just getting started with this project, but I like what I see so far!
