Project Server 2010 Planned Vs. Actual Report

I need to show Planned resource hours vs. Actual resource hours and we are using Project Server 2010. We are baselining, so I understand the "planned" information needs to come from there. But here's the catch: I need to show Planned vs. Actual by MONTH. Once we load our project plans with tasks and resources I need a way to be able to show what has been planned for all of our tasks by month so we can compare that to timesheet actuals that are submitted. So far I've only been able to show Planned Vs. Actual in one lump overall sum.
