 If one of the existing reports is close to meeting your needs, but requires further PHP or SQL customization, you may simply make a new report based on that report. To copy a report, find the class-name of the original report within the `civicrm/CRM/Report/Form/` directory in the CiviCRM repository. Then run the `civix generate:report` command using the copy option from with your extension directory.
