If all the 'forms' are in a single document then just use cross references to the original information. This can be a bit fiddly unless the forms use form fields or content controls, so for preference I would suggest a VBA userform to collect the common data and write it to bookmarks or document variables throughout the document as required. This is not as difficult as it might sound - see
