howto setup a site number for pdf-export

The pdf-export is a nice feature for a story. I want to see the site-numbers in the exported pdf.

Howto setup site-numbers for a story?

What do you mean by site-numbers? Page numbers?

Yes, I mean page-numbers.

Jw, could you tell me why you need those page numbers? Doesn't your PDF viewer already have the way to see the current page number?

For example: like by an presentation

• in footer or header
• in different format: 1,2,3,4 or 1/4,2/4,3/4 (nice to have)
• in different styles: numeric or alphabetic (nice to have)

backgroud: I use wireframe-pdfs in workshops and meetings.
