InDesign’s Paste In Place works across multiple documents
When you want to copy an object, or group of objects from one page of your Adobe InDesign document, and paste it in the exact same spot on another page, you simply hit Command + C to copy, and Command + Option + Shift + V to paste it in the exact same spot. Most people know about this function, but did you know it works in other open documents? As long as both (all) your documents are exactly the same dimensions, Paste In Place will work between documents.
