InDesign includes a feature where when text frames are flowed over several pages it is possible to automatically insert the Continued on page number at the bottom of the first page and the Continued from page number at the top of the next page. It is activated by choosing Type→Insert Special Character→Marker→Next or Previous Page Number when the Continued text frame slightly overlaps the content frame.
Is this already available in Publisher or is there a plan to include it?
