If I've understood your post correctly, I'm not sure why you wouldn't just crop out the top and bottom of the page and then if the page is enlarged too much by doing that, you could could zoom past 100% and change the page alignment to center. Another option would be to just use the vertical scrolling display mode with the top/bottom of the pages cropped. Otherwise I'm going to need a detailed description of what changes you would proposed be made to address your current use case scenario that accounts for all possible page sizes, settings and uses by other users.

Thanks,
Mike
