Filter with logic 'AND'

Hey,

first of all, it’s a very nice plugin but there is a problem I’m trying to solve.

Is there a possibility to filter with a logic ‘AND’. For example I wannt to filter category1 AND tag1. This combination just fits to one post. But I can only filter either category1 or tag1. It just shows either the archive for catogory1 or tag1.

I am using this shortcode:
[searchandfilter fields=”category,post_tag” types=”checkbox,checkbox” headings=”Categories,Tags”]

Tanks in advance.
