well you have to understand that excel has 2 different kinds of page breaks natural breaks and manual breaks. There is nothing you can do about natural breaks, they cannot be removed but they can be pushed down. So it is entirely possible that doing something like what you want could result in having some very short pages with only a few rows on them and some very long pages.
With that said, it certainly is possible to insert manual page breaks at certain rows, but try to understand the above that will occur.
I just wanted you to have the information so you can decide how to proceed
