Global report defaults

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.
Thanks, Jonathan

I can take it that this cannot be done then? I couldn’t find it under help. I’ll repeat my question as a Feature Request.
