Create NTA IP Address Group by API

Hi Guys,

currently I have the challenge to create "NTA IP Address Groups", at the moment this is a manual process by either creating an xml file and importing this into NTA, or in case of minor changes, editing the list manually (see screenshot)

I can see that some of the information is stored in Orion.NetFlow.IPAddressGroups, but not the actual Range.

Is there a Verb to add an NTA IP Group? Is there any way to add an IP Address Group?

Thanks!
