Category matching

I have a few categories that I have pages and posts about.

I am using the testimonials sidebar widget on the page and post templates.

Is there a way, using the sidebar widget, to filter the testimonials so that on a page/post marked Category A, only testimonials marked Category A will rotate on that page/post?

I am using the free version, but would be happy to upgrade if this is a feature of the paid version.
