EasyTime Extend

There does not seem to be an easy way to extend time usage for either a user or a device without find the user, finding the device that is under their profile and knowing which one they are currently using and then day and then to move the slider to add more time. Then afterwards I have to go back through all of this to return the user to their original time constraint. 

Ideally there should be a way to easily extend time for the user by simply press a button and simply add time until mid-night (when the time usage clock starts all over again) regardless which device they are using.
