Massive add to NCM for non added devices

Massive add to NCM for non added devices

Hi,
I'm running enterprise edition OPM with NCM add-on.
I have recently upgraded my NCM licence to i could cover all my devices with NCM.
So, i have a lot of devices that OPM monitors that are not added to NCM.
Is there a way I could filter them out, and efficiently add them to NCM?
