Is there a way, on the blog posts element, to exclude a post if it has a certain category? Most of my posts have two categories. I want to be able to exclude a post from the element if it has a certain category. Right now, I only see how to include it if it has a certain category. So if a post has category 1 and category 2, and I tell it to dispay posts with all categories except category 2, it will still display the post that has category 2 because it has category 1. Is there an option to *exclude* by category?
