Change report defaults globally

In the reports if I change the paper size from Letter to A4 it accepts it as a global change; I don’t have to change the paper in any other report. Is it possible to do the same with fonts where I’d like to change Times Roman to Calibri and have RM remember it in the report I change it in, and–even better–accept it for all reports? Ditto colour scheme. I haven’t found it in Help. I couldn’t do it globally in RM7, but I could in a specific report, ie once I set the font etc in (say) a Places report, I wouldn’t have to do it when running a Places report in future.
Thanks, Jonathan
