add two of my books to existing series

[M.]

My current series I am authoring, "Raiders of the Dawn", contains Raiders of the Dawn, Guardians of the Sword, Bridge of Shadow, and upcoming Dawn's Gate. But only the first two appear linked to this series. How do I get "Bridge of Shadow" and "Dawn's Gate" added as books 3 and 4 to the "Raiders of the Dawn" fantasy series?

It takes a librarian. Added to series: https://www.goodreads.com/series/2154... It will take a while to show properly on your author page due to caching.
