Changing the "n" value in page numbering

I have a document with multiple sections, and I'd like each section to be numbered as "page 1 of n".  For example, I want pages 3 - 94 in my 157 page document to be listed as "page 1 of 92"..."page 47 of 92"...etc.  When selecting the page numbering option of "page 1 of n", I get "page 1 of 157"..."page 47 of 157"...etc.  How do I change the "n" value to reflect the number of pages in each section?
