This information has only partially helped me (still trying to figure out how to adjust my script to account for it), but maybe it'll help others more. I've been struggling with the same problem, and finally figured out that if you go to "Group Level Properties" and change DataPageSize to something other than 1, you can display however many records you want on each page -- within reason, of course: 25 or 30 might be reasonable depending on the amount of data each record will be displaying.
Hope this helps!
