No, there is no way you could combine the folders. You can either start over, or continue using the way the folders have been generated. It's not a bug or an error with the application, just that the software doesn't have this feature. I have tried to look on official website, but the manual doesn't specify anything related to this procedure.
However, there is a troubleshooting manual available for download that you can use. Download and open it and read through the topics. This is the only way to acquire additional details about the application.
