Need help adding new books to current series

[Natalie]

Hey! I was hoping I could have the next three books in my series added to the current series so they all show up when someone clicks the series name? I haven't been able to figure out how to do it myself.

(book 4)

(book 5)

(book 6)

Thank you so much for your help!
