Hi! I use Affinity Publisher and MacOS I am very pleased! and love the program. But. I am working on a whole book 1.000 pages and I am almost done. But! I would like to add an extra page or spreed in the beggining/middle and therefore move everything one spreed. Is this doable? The problem is, I think, is when I put in all the text I did it in one single paste (copy/paste) and then I press the little markers / arrows on the right side of each page which then "sends" the text and lets it flow into the next page / spread or the text box in the next page / spread. So the entire book is a long mass of text that runs through the entire layout, 1,000 pages of layout in one long flow. I get the impression that I should have pasted (copy/paste) one chapter at a time? From the beginning? And that it is now not possible to suddenly insert an extra spread in the middle and then have everything move afterwards? Or? So my question is whether it is possible to insert two extra pages, one spread, in the middle with new text without destroying all the layout that comes after? all the pictures I have placed etc. etc. etc. Thank you for all your answer!! Best regards Marcus
