I've checked in a new version of pdf2csv.pl in the repo. It has additional possibilities for the extra columns:

Code:

--extra -x KEY=VAL
            Add additional fields with value *VAL* to the CSV.

            *VAL* may contain substitution strings in the form "%{XXX}",
            where *XXX* can be one of "startpage", "endpage", "pages" (the
            page range) and "pagecount" (the number of pages in the PDF.

            This may be repeated.
