ID3 Tag series does not exist. How can I add series to my audiobooks when not using the folder structure?

Describe the feature/enhancement

I want to add series to my audiobooks. But there is no id3 tag that is called series: https://exiftool.org/TagNames/ID3.html. My taggers mp3tag and mediamonkey cannot add this tag either. The documentation says there should be one: https://www.audiobookshelf.org/docs#book-audio-metadata So which ID3 tag are you using to add series? Or are you just using the folder structure for this tag?

u can add custom tags and profiles for tags (to switch) to mp3tag ...

You're right thank you. Did not think it would be possible to add arbitrary tags in the extended tag section when clicking right on the track in mp3tag. Thats a good way to add that tag easily.
