Report for Average Utilization by Time of Day

I'm having a heck of a time trying to figure this out.

I need to create a report that I can run monthly that will average out the utilization by hour of day.  I know that I can create a report that does this for a particular time range (like 8-5 or even 12-1 etc.)  However, what I would like is something like the following:

Device 1

     Interface 1

          12:00     Average utilization     Peak utilization

          01:00     Average utilization     Peak utilization

     .     .. So on

     Interface 2

          12:00     Average utilization     Peak utilization

          01:00     Average utilization     Peak utilization

          .. So on

Device 2

     ... So on

Is this possible?  This would allow me to create 1 report across all of our sites showing which hours of the day have our heaviest usage.  So far I have only been able to do this by creating a new report for each hour of the day which is a major pain.

Any help would be greatly appreciated.
