The Report Wizard can be used to create or edit either your default reports or reports associated with existing paths.
The wizard does not allow you to edit all settings but on every page there is an Advanced button that takes you to the Reports dialog where more settings are available.
Each page also has a Finish button, which applies any changes made so far for the current session only. If you want to make the changes apply to future sessions, click Next until you get to the Finish page.
