# biblatex: separator for citing multiple sources, some of them with page, some not

I'm using biblatex for my references.

Normally, if I use \cite{source1, source2, source3}, I get a citation like

[3, 45, 98]

If I now want to give a page number for one of them, it looks confusing imho, as I should get (did not try it out up to now, honestly)

[3, 45, 78, p. 23f, 98]

So imho it would make sense to change one of the separator from a comma to e. g. a semicolon like:

[3; 45; 78, p. 23f; 98]

Question 1: Does that make sense, or are there other conventions for citing sources with and without page numbers together?

(Up to now I collected the citations without page number in one cite command and added singular \cite[][p. xy]{} commands for those with page numbers., so I'd get:

[3, 45, 98][78, p. 23f]

)

the \cites[]{}[]{}[]{} could also do that, but it also uses the same separators for entries and postnotes.

Question 2: How could I change the separator globally for those number-citations from comma to semicolon in biblatex?
