Is it possible to make biblatex output page counts for both the regular pages and the roman-numbered pages, for example:
Cook, Theodore Andrea. The Curves of Life : Being an Account of Spiral Formations and Their Application to Growth in Nature, to Science and to Art; with Special Reference to the Manuscripts of Leonardo da Vinci. — London : Constable and Company, 1914. — xxx + 479 p.
Here there are "30 pages + 478 pages" in total. Thanks!
