Tv series collection

Can you add tv series collection for series spin-off, sequel, prequel, canons…?

Eg Arrowverse - Arrow, Flash, Supergirl, Black Lightning, Legends of Tomorrow, Batwoman, Superman & Lois…

Thanks

Do you mean on the details page?

I can only load the data from TMDB. Not sure if the data are there https://www.themoviedb.org/


Something like the attached, where a movie franchise is part of a collection.
Not sure if the data is in themoviedb, as im referring to tv series… eg Arrow TheFlash Supergirl etc are part of the Arrowverse collection
