GSM backup for Stickup Cams using Ring Alarm base station

I own the ring alarm kit with the Protect Plus plan, I find GSM backup very useful when WIFI goes down. I am sorry to note that the stickup cams cannot rely on the GSM network of the base station of the ring alarm in case of disconnection of the WIFI. It would have been a very useful feature in order to have a full foult tolerance system.
