Dell OMNM Traffic Flow - custom graphs based on Network Block

i have a customer who has implemented Dell OMNM with a force10 C300 sending Sflow data to it.

the collection is going fine and you can see graphs under the traffic flow section.

Ultimately he would like to see historical bandwidth graphs based off of this sflow data for certain ip ranges.

So In/OUT bandwidth for all traffic to/from  192.168.1.0, 5.6.7.0/24, 3.2.3.0/24,  as seperate charts.

Basically an MRTG style graph

Is something like this possible?

thanks,
