One Button Block/Lock option

Currently I do not see a way to block or lock user either from a profile perspective or from a device perspective. I find my self flipping through a lot of dialogs and setting to completely block/lock down a user and/or a device.

There should be an option to block/lock either based on a user profile or a device. Essentially preventing the user from using their device until unblock/lock. Kind of like a panic button.
