If you would like to add a new session to your schedule, you can simply use a template to quickly add the new session.
Using one of the methods to "Create Sessions" (which includes creating classes and workshops) you will find a "Session Template" button or dropdown menu to select.
Once you select the template, it will populate the fields to create a session with the template settings.
If you need to adjust any of the template settings, you can simply override the input fields pre-populated and continue creating the session.
If you do adjust any of the fields you can override the template and "Save As" so all future cases will have the updated template.
