Can devices be moved?
I have a configuration for mobile devices, with the block lists I have in place for that configuration, Facebook is inaccessible and needs to be.
Rather than reconfigure those devices (the family members don't live with me) can they be moved to a new configuration where Facebook is allowed?
So your (remote) family devices and your own device share the same ID, but you want to different Facebook related settings and not change the ID on those remote devices?
I'm afraid this means you would have to create a new configuration for your own devices and use that at home (change the ID on all your own devices).
