[Observium] Interface description, auto-add to billing?

I could have sworn I had seen something where I can enable an auto-add feature in order for ports to be automatically added, into the billing piece, with a particular pattern in the port description. Is this something that is available or will be available? i cant seem to find it again for some reason and I remember even seeing the pattern that was given, which would need to change in my particular instance. Any ideas on this one?
