[Request] Scan subdirectories for series and automatically create collections for series within the same subfolder

[veerpandya]

My current folder structure looks like the following:

Series Name > Series Season Name [anidbid-12345] > Name - 01 - [some][info].ext

As AniDB does not support traditional seasons, a nice alternative would be to group series inside a folder and then have that folder be scanned in as a collection. This would greatly aid in adding new series to a library, and it would keep the main library directory more organized.

An example of this structure would look something this:

Anime Library >
        Initial D > Initial D First Stage [anidbid-135] > Initial D First Stage - 01.mkv
        Initial D > Initial D First Stage [anidbid-135] > Initial D First Stage - 02.mkv
        Initial D > Initial D Second Stage [anidbid-145] > Initial D Second Stage - 01.mkv
        Initial D > Initial D Second Stage [anidbid-145] > Initial D Second Stage - 02.mkv
        Initial D > Initial D Third Stage [anidbid-625] > Initial D Third Stage Full Movie (2001).mkv
        Initial D > ...

The base Initial D folder would be located in the root of the library. When scanned, Jellyfin should check within the folder and create a collection titled Initial D and then add the contained series to that collection.

This can be added once https://github.com/jellyfin/jellyfin/pull/9407 is in a release by having a custom id for different seasons (the anidbid has to be in the name as shown in your example).
