Resource Group Efficieny Report

When I run this report for a period of time I get a recap of what the
charges where by resource group

Is there a way to get a detail report of time charge to a resource for
a given period of time.

This way I can see what parts where run and which employees charged
time to the resource.

Looking to drill down to see what makes up the # from the Recap Report
I am getting right now
