Dealing with episode numbers of shows with multiple seasons

[simsands]

An example:

The SubsPlease release for Shinigami Bocchan S2's first episode file name is [SubsPlease] Shinigami Bocchan to Kuro Maid - 13.mkv

I want Jellyfin to view this as the first episode of Season 2. Ie, with metadata Season number: 2, Episode number: 1
I use Ani-Sync to automatically update Anilist, and if the metadata is incorrect, Ani-Sync either fails, or incorrectly updates the list.

I've tried three different folder setups:
- A base folder 'Shinigami Bocchan to Kuro Maid' containing the episode file
- A base folder 'Shinigami Bocchan to Kuro Maid' containing a subfolder 'Season 2', which contains the episode file
- A base folder 'Shinigami Bocchan to Kuro Maid Season 2' containing the episode file

Neither of which actually solves my problem.

Is it possible to fix this without manually updating every episode file?
