I looked into this and I'm unclear how much customization is possible.
Here is a link to my attempt at this a couple of years ago. It basically "abuses" refentry.
I never did dive into the man page or PDF dynamics of this particular change but it seemed to solve HTML pagination without negative consequences and with minimal risk of unintended consequences since only the markup on the pages we want to alter is changed, not global configuration.
