Hello. I hope this is a quick and simple question for y'all.
How does one mark a book with more than one genre hierarchy? For example, if I have a book in Nonfiction.Memoir but would also like to add the genre Humor, how would I do that?
I tried separating them with commas, but it simply appends the comma and subsequent non-genre to the name of the one genre that it creates (e.g., Nonfiction.Memoir, Humor, where "Memoir, Humor" is a single subgenre of Nonfiction). I also tried to drag the book to the Humor genre, only to have it replace the already selected Nonfiction.Memoir.
Help please.
Thanks!
