I made a quick collection of images I wanted to use in the book module. I move to the book module and worked on a book and hit "created saved book" and named it. It shows up as a collection. When I come back to work on the book I only get the initial images to work on but I want to use additional images that weren't in the original quick collection. Even when I add to that quick collection, the only images that the save book will let me use are limited to the original quick collection. What do I do to access additional images for this book???
