Does anyone know how to change the Document Map root text?

hi, guys
Does anyone know how to change the Document Map root text? For example, i have report, the file name is sc.rdl, and then the root is sc. Apparently this is not good. I am thinking is there a way to change it.If you are using the ReportViewer controls in VS 2005, set DisplayName on either ReportViewer.LocalReport or ReportViewer.ServerReport, depending on the mode you are using. Setting DisplayName will also affect the generated file name for export. If you are connecting to the server directly via url access or using Report Server 2000, there is no way to change this value.|||

Brian, I want to be able to assign displayname at report design time....then be able to extract it out for display purposes when using the reportviewer control connecting to a server report. Doesn't sound like it's possible but is this something for a future enhancement. Currently, using the report viewer control, there's limited properties exposed when using ReportViewer.ServerReport.<property>. Would be nice to get at the author, description, etc. (and have an additional displayname property available).
