Hi there @unclewoja. Thanks for posting your first thread to our Community.
Currently there is no workaround to create folders in Salesforce automatically upon set up. The process is manual and all the steps to set it up can be found here: https

Wish I could be more helpful and provide a workaround. Please get back to me with any further questions.
