A command to advance the merge to the next record of the source spreadsheet is a pretty basic feature in Microsoft Word. For example, if you have a column labeled "Names" on your spread sheet and want your final merged document to list more than one name from the column on a single page, there should be a code command to make it happen. In Word, the command is <<Next_Record>> . You can read more about it on Microsoft's support page: https://support.microsoft.com/en-us/office/set-the-rules-for-a-mail-merge-d546ee7e-ab7a-4d6d-b488-41f9e4bd1409
