Custom block pages dependent on AD group membership
When a website is blocked, display a custom webpage which is dependent on the AD user group membership of the user. This would allow, for instance, a member of an "Internet Banned" AD group to have a block page which tells them they are banned from accessing any website, instead of the current message which refers to the category of the website - eg when trying to get to google, blocked because Search Engines are banned.

This is also good for us who are IT providers and each policy, with AD group is technically a different customer, this is quite common in large company's, gov and healthcare.
