Customer Port Group is displayed differently than the other port groups

We have been using the Port Description Parsing for a while for Peering and Transit. A couple of days ago we also started using the Cust Identifier for our Customer Ports.

I have noticed that the Customer Port Group does not display a total graph at the top of the page. This is something we are so used to from the other Port Groups and it is something we want to see.

This is probably because the Port Group is linked differently. (/customers instead of e.g. /iftype/type=transit)
Is that supposed to be so? Could this link be changed to /iftype/type=cust? Then everything would be consistent...
