As an author, I'm finding it challenging to maintain consistency across all the books in my series due to the lack of a feature that allows sharing a single codex among all the books. Currently, I have to move each entry over by hand, which is time-consuming and inefficient. I suggest implementing a 'bulk move' action that would allow me to easily move all entries in the codex into the 'Series'. This would ensure that all my books are synchronized and consistent.
