I downloaded 2 book chapters manually, and Zotero saved all the metatdata perfectly including the book section authors and the editors of the book. However, when I downloaded the rest of the book as a zip file, extracted the PDFs of each chapter and uploaded to Zotero, it did not include the book editors for each book section.

Is there a way to add the same book editors to all book sections without manually doing it?

I did search but didn't find this question, apologies if I somehow missed it.
