Address Grouping - more information or feature request

In the feature list of 4010 we are running there is:

1. Address Grouping - Create monitoring and reporting groups based on IP addresses or applications

If I give a look at the "All IP Groups - Dashboard View", I like to see how much bandwidth is using one particular group of ip (1 group equals 1 range in our configuration) but how can it be revelant or useful because it is not linked to any router? Can you give me some information on that please?...

I think a very interesting feature is the ability to see how much bandwidth a network range that is behind a specific router is using. If you have one router with 10Mbits/sec and with 4 network ranges behind, I think it is very useful to know how much bandwidth (out of these 10Mbits) is using each range.
