I am designing a stapled booklet on Figma. The finished booklet will be A5 pages, but I have designed the booklet as A4 sheets, to be folded in the booklet. I went to the print shop, and their software couldn't handle the imposition, and told me I had to cut each A4 pieces into A5 pieces with the correct numbers. Is there an easy way to do this? My LLM is telling an insanely overcomplicated way of doing it. I just need to cut the A4 piece in half.
