I have a book that is in a 6×9″ layout and I would like to make an alternate layout for 8.5×11 (and other formats) then export both as independent books to PDFs. How can I do this or is there another better way? I thought alternate layout would be the way to go, but I don’t think I can export the alternate layouts for all my chapters/etc., from the book menu without including ALL the pages from each layout?
