It would be extremely helpful to be able to create (and save to edit later) more than just 1 config file for iOS and one for macOS.

If you're managing more than one device and would like to block/allow different settings or apps for each device, you have to create or edit the file from scratch each time.

I think a good solution could be a profile for each device(or maybe each cloudflare account) where you can store the current configuration for that device or that person's devices. That way you can pick up where you left off.
