Exclude category from all categories

First off, I love this plugin! It’s a real timesaver. But I have a request.

I have a featured post that has a ‘featured post’ category, that I have showing at the top of the posts page in its own post grid. Below that, I have a post grid that is showing posts from all of the categories. The problem is that the featured post is also showing there. Is there a way to exclude my ‘featured post’ category from showing in the all categories grid?
