I'll talk to UX team if we there would be also alternative way to go than have button. Anyway I entered a feature request for this (111968).
Is there anyone else who is suffering from the same issue?
I have the same problem. i have over 500 subnets that i need to organize and it doesnt seem to be very easy to group. I imported from the eng toolset and i have a lot of cleanup to do. I also wish i can search or filter for a subnet and not just IP address as we reserve ip's a lot and need a fast way of getting to the specific subnet to do a manual scan or edit settings.
adding +1, thanks.
