Ok, gotcha! Could you point me to an example of how that page number could be printed somewhere? My goal is this, HTML:

Here's text with anchor text.

Becomes a paragraph in the pdf document: Here's text with anchor text[1]. And then in the footer, is a footnote: 1) See one page #7. ...where page 7 is the where the /some-blog-post is now located in this pdf. Does that make sense?
