Page navigation on Next Page tag

[katootje]

Hi, the site I'm working on (sorry, behind maintenance mode) is using the NextPage tag to break long pages in more shorter pages. Genesis automatically generates a page navigation with numbers.
I found this link in codex to alter the output:
http://codex.wordpress.org/Styling_Page-Links

But how to alter the output in Genesis. I would like something like:
<< 3 | 4 | 5 | 6 | 7 | >>
so if there are a lot of pages, only 5 numbers are shown
The designer also like to style the numbers, so if there is a way to add a class to the normal numbers and to the active page, that would be great

NB I'm talking about pages... not archive pages for posts
