First populate the Annotated Location field for each device with the email address of the assigned user. Then, deploy this extension to users that you want to block. Configuration options allow for a custom block page as well as preventing blocks if an assigned user matches an expression regardless of who signs in. Note: Only deploy this to users that you want to block and be sure you've populated the location field of their assigned device with their email. You can also use a * to allow everyone on a specific device. Source code and additional details can be found at: https://github.com/matthttam/oneTwoOne/tree/master
