There isn't a way to do this in reports currently though it has made it to the What We Are Working On for DPA Page. "Reporting on Resource Metrics".
The closest thing I could suggest for now is going under the trends view drilling into a time you want to see resources for and click the resources tab under the graph. Perhaps changing the resources that are displayed with the menu to be the items you are interested in seeing. You can then click the email icon and send that as a report with the charts. I know this isn't the same as it isn't a scheduled item. I hope that helps some.
