More than one portfolio

Hi.
I like all in your plugin.
Just one thing.
I want create the new portfolio on other page with other categories.
But when I generate the new short code and insert – I see all portfolios which I created before.
I can’t find how to mark which categories(or portfolios) belong to specific short code (id).
Otherwise I don’t see reason to generate new short codes which display same portfolios.
Adwise please.
Thanks!
