Custom Notification Content Not Displaying Correctly

I have a follow-up question. We have been extensively using query notifications for almost all create/update queries in our application. Is there any shortcut to configure event handlers for all queries?

Also, I was reading about the global flag in the new notification settings that controls notifications across the entire application. What does this flag control once query notifications are removed?
