There is no way to automatically do that in PSM.

The closest thing you could do is have conditional layouts based on the length of the text in your database. For example, you could have two layouts, where one layout would always print, but the second one would only print if the length of the text is over 200 characters. You could use the "mid" function to display characters 1 to 200 on the first page, and then 201 to the end on the second page.
