Same was as usual, but break the link between the second page and the first page. This lets you 'delete' the page number off of the first page and retain the second page. You can format the numbers if desired to restart them wherever you want.
Mixing is a pain though, like a TOC is generally 'ii' if its the second page and the first page is 1. That takes some playing with the pagebreaks and new sections and things like that. I have a friend that's super good with word.
