As a work around, you could try changing the page order so that pages are duplicated, Then you cropping to adjust each page individually.

This probably only applies to pdf files (which is what I use) and would be a real pain if you have to do lots of files.

Another possibility is that you set the song display to "vertical scrolling" (see this).
I believe that you can use smart buttons to toggle scrolling (apart from trying it once, I haven't needed to go this route).
