Can I filter on unanswered questions and also on the category, or just on one thing?

I would like to filter to see unanswered questions in the categories where my expertise is, so that I can try to help people who haven't had any response yet -- is this possible?

I see where I can filter on unanswered questions, but the questions seem to be in time order so I have to scroll through and scan for ones in categories I can help with. I also see where I can filter by category, but then I have to scroll through answered questions looking for unanswered ones.
