License Configurations (Configuration Keys) and Configuration Key Groups

There used to be a method of importing/exporting configuration key files. The old method wasn't great, but at least we had something. Now there's something called "Configuration groups" but they don't work. Groups only allow turning Configuration keys on but not off. We need to have these working so when a production system is put into maintenance mode, there's a predictable and repeatable method of turning keys off. There should be a button for a Configuration group that says "Turn all these on" and "Turn all these off". Pressing this button should update the checkboxes on the Individual Configuration keys.
