FM 10 - How set up Roman Numeral page numbers in preface?

I want to use Roman Numeral page numbers in the preface, but normal numbers in the document (not book).  How do I set up a "first pages" section for Roman Numerals?  Using FM 10

I have  Mastering the Basics of (and More) of Adobe FM 10, by Janet Underwood, but cannot find anything in there that helps.

Yours, Earle Fox
