Inserting number of pages (not page number)

That’s what I was afraid of. This means that I have to go through all the chapters of my thesis, check all the footnotes and change from the ‘‘Edit Citation(s)’’ menu the information about the page numbers. From this menu, remove for each footnote all that appears in the box ‘‘pages’’ and enter the information in the box ‘‘suffix’’ by adding the letter ‘‘p’’ before or after the number as appropriate, without forgetting to modify the ‘‘References Types’’ and remove the ‘‘Cited pages’’. A enormous work!
