Quoting a reference using biblatex, it is possible to add an optional argument to cite in order to specify the page number that is being quoted, such as in
\cite[20]{foo}
which will produce something like "[Foo, p. 20]".
My question is if there is some package or some hack that will allow to do the same without the "p.".
The goal is to be able to cite specific paragraphs, rather than pages. The paragraphs happen to be numbered by roman numerals, so the idea is to be able to do something like:
\citep[XXVI]{foo}
and get something like "[Foo, XXVI]".
