Create Custom "Folders" Within Libraries

This might be hard to explain.....I have a Library within my Plex Server called Learning where I have some courses that I have downloaded. However, when I view the library within Plex it is not organized based on the folders on my hard drive. They are all jumbled together.

My goal is to have something like TV Shows where I can select the first course and have all the "episodes" listed within. I know that I can do something like this with categories and tags, but is there an easier way that I am missing?
