Is there a way to list 2 categories on a page template (similar to the portfolio section), but have only posts from those 2 categories show up. In other words, I have the category Holland and then I have different categories for tour types in Holland. I want a page that lists posts categorized with Holland and then a particular tour type. I don't want the page to include all Holland posts and all the posts from a particular tour. Just posts with both of those categories.
Is this possible?
