When you open Print Organizer from the sheet index, the Advanced Settings option is not available when modifying print properties. To access these settings, you currently have to open Print Organizer from the DGN file, create a new (blank) PSET file, and then add your sheets to it. This workaround is time consuming and inefficient. Advanced Settings should be accessible directly when opening Print Organizer from the sheet index so print properties can be adjusted without extra steps.
