Custom notification setting for all cameras

(If this exists, I can't find it.) The Issue: if I want to turn on notifications for every camera, I have to do it for each one; we have 3.

The Idea: I want to create custom settings, such as the following: When system is OFF, I will not get notifications when a camera detects motion. If the system is on HOME or AWAY, I will get notifications of motion from any camera that detects it.

In other words, my custom settings will NOT require me to turn notifications ON or OFF for each of my 3 cameras every time I go away or go to sleep. I keep notifications OFF for all cameras when we are home and will be doing things outside. Having to go into settings for every camera and change notifications is a big pain in the arse.
