Hello there,  @aibranossian  Welcome to the Canvas Community.  Thank you for posting your question.  If you would like to create a course development shell (sometimes also called a "sandbox" course), you should be able to reach out to your school's local Canvas administrator or someone in your school's Online Learning/eLearning department to see if they would be able to set up a course shell for you.  This is something that we cannot do here in the Community because we only have access to our own school Canvas environments...and we do not have access to your school's Canvas environment.

I hope this information will be of help to you, Agatha.  Sing out if you have any other questions about this...thank you.  Stay safe, and be well.
