Howdy Julie!
That should definitely be possible. It depends on how you (or the theme dev?) have setup the Courses post type. We can definitely walk you through this here if you have a Pro account, but would you mind logging in and opening a topic in the support section for that?
If you don’t have a Pro acccount, there is still a community of volunteers on WordPress.org: The Events Calendar . Customizations like this do not always receive a lot of volunteer help, but sometimes they do.
Let me know if you have any pre-sales questions or anything. Thanks!
