Insight Management App and Access Control

Hi,

Not sure how many of you use Access Control Lists (Allow Mode) with your configurations.   I have recently added three WAC 510 APs to my configuration.  Prior to that I just used a Netgear Nighthawk X6 R8000 for all my Wifi needs.  Being somewhat obsessive about things, I have been using Access Control for all of the devices that connect to my router.  That ACL is still in effect now, even though I have all but one wireless devices now connected to the APs.

Although I'm not sure why I'm so obsessive about this (another topic), I would like to transition my Access Control from the router to the APs.  I am managing those APs using the Insight Management App.  I haven't been able to find any way to batch input allowed MAC addresses for the APs.  There was a way, although with some bugs, when I was managing the APs locally via a web browser.  Is there a batch method, or do I have to painfully enter the MAC addresses one at a time for each AP via the app?
