Report Accessibility by User Roles

Report Accessibility by User Roles

Is there a way to lock out user roles from viewing certain reports? Our administrator users need to use many of the standard reports in Zoho. However we only want the sales people to be able to use a handful of reports. For example, we don't want sales people to have access to the "Sales Person's Performance Report".

I saw that if I create a new report folder, I can assign users to access it. But I can't find a way to assign users to the standard reports. Any suggestions?
