How do I assign a course page in CoursePress Pro?

I have installed CoursePress Pro on my website but the design doesn't look good. I am looking to change the look of the page. I am currently using X Theme from which has a great visual page builder (Cornerstone). Is it possible to create a page using Cornerstone (and shortcodes) and assign it as a Course page so that all my future course will be displayed using that design? My coding skills are limited and I am looking for the easiest solution which allows me to change the look of the page and keep it safe during future updates.

Thank you.
