Opmanager 12.2

I have about 100 switches listed in my opmanager, If I don't want to receive notification when some interfaces going up and down I have to unflag the status PO option? but I have to click in the interface one by one??? No multi select option?? (it was there in the OP 11)

For examble I have clients switches and I receive the notification every day when the users shutdown and turn on the computer, because the interface go up and down, but I want to receive this notification only for the trunk interfaces, because these interface must be always up!.

No way to automate this procedure, i have about 5500 interfaces!?

thanks
