That's what we have now:
1. Paper size and orientation are always set to the latest selection in wizard.
2. Paper margins can be defined for custom format.
3. Regions margins along with major formatting options can be defined in the Report Style (last page of the wizard).
That's what I do:
1. Run wizard to create a new report
2. Check "Create blank report and finish now"
3. Done
Report has paper format and orientation set to the latest settings I have made previously in the wizard, no need to change them.
Page margins we can set in custom format.
