Create a New Historical Bandwidth Utilization Report

It would be nice if with in Solarwinds you could run a report that would allow you to select your Internet connection interfaces and run a report that shows utilization during business hours.  The report would allow you to select the interfaces to monitor and also select the time frames from which you want to see the data.  The data would also be represented in both bps and % utilization.  In addition, this report would have to keep the data separate in someway so that the data would be compressed over time.  The issue we have is getting an accurate picture of our bandwidth usage to pass on to management.  We have to create a custom report and even then data gets compressed as time goes by so by the end of the month, even though you select only working hours and exclude weekends the data is still distorted because of the data compression after 4 hours and a day and a week and so on.
