Thanks for posting this in the global Community!
I am sorry no one has responded to you on this. I wanted to pop in and provide you with some helpful trick on this question you have posted.
As a student, you can customize what courses are displayed on the dashboard. You can just click on the Courses button and select "All courses" to look at all of your courses you have taken in Canvas. From there you can click on the star for any courses you with to show on the dashboard. HERE is a guide on how that works.
Hopefully this helps!
