I often work on publications 500-1,500+ pages in length, which requires me to use several documents, threading text full of graphics in each document. I cannot contain everything in one document (too large, will crash, even though all graphics are linked rather than embedded). If there was a way to automatically allow text to overflow into new documents after a set amount of pages per document, that would be amazing. It would save me tons of time when manipulating content and then aligning before preflight. You could even keep it to where this feature only works if used in Book since that's already incorporating page numbering and styling in blanket form for all documents included. Thanks for considering!
