Possibility to order report parameters

Hi,

I'd really like it if I could sort/reorder the parameters in my report, in the fields list, or even separate them in maps. At the moment I have a report with manymanymany parameters, and I have a certain order in them, but if I forget one halfway and add it later, there currently is no way to put that last parameter halfway, next to the parameters where it belongs. Creating different maps of parameters would be even better, but simply changing the order would be great already, to make the list of parameters understandable. Thanks!
