Inserting number of pages (not page number)

Here is for example in Footnotes templates my reference type for a book :

Author, Title| [ Translated Title ]|, trad. de: Language| par Translator|, Number of Volumes t.|, Place Published|, Publisher, coll. « Series Title »|, Year |[Original Publication]|, vol. Volume, p. |Cited Pages.

if I select ‘‘Edit Citation(s)’’, ‘‘More’’ and I write the number of pages in the box ‘‘suffix’’. here is the result: 

Peter Murray et Linda Murray, The art of the Renaissance, New York, Praeger, 2013 [1963], p. 286 p.

Can’t we temporarily remove the ‘‘p.’’ that precedes the numbers?
