Add Studio: "Som Livre"

[vhugodd]

How is it possible to add "Som Livre" as a studio option for movies?
That's a Brazilian record company that makes video productions like "Xuxa Só Para Baixinhos" (https://www.thetvdb.com/movies/xuxa-so-para-baixinhos).

Here's the wikipedia page for Som Livre: https://en.wikipedia.org/wiki/Som_Livre
and here's the official website: https://www.somlivre.com/

Thanks!
