How are CoursePress Courses Ordered?

I have read in other forum posts that the CoursePress courses are ordered like regular WordPress posts, but that doesn't seem to be the case. As regular posts are ordered by Publish Date, but it appears that CoursePress Courses are ordered by Modified Date. In my list of courses, if I edit/update a course it jumps to the top of my list.

With this being said, is there any way to establish a specific sort order to the courses? We have specific Products that will have new courses added, but occasionally one of the courses will be a simple training that we don't wish to have at the top of the list. So we'd like to have an integer (10, 20, 30, ...) based index that we can use to sort the courses. This way we can manually specify which posts will be at the top of our course list and which ones will be at the bottom.
