Feature Request: Block or allow individual devices based on time schedule

I completely agree with you and definitely it's a needed feature to bring more easy processing through the acts. Getting the feature option to block all devices is a effective one, no doubt about that but without a single device blocking the entire use becomes less valuable. I do work for a professional resume writing service (website) and I have to use some kind of tools during various work processes. Hope this feature will be enables sooner rather than later. Eagerly waiting for the chance to make use of that advanced single device blocking option.
