We should have the ability to use the checkbox selector for blocked categories within a policy at a subcategory level. For example, Social Networking, should have additional options that show as sub-categories for a more granular approach. This would be in contrast to having to create an allow category manually and adding the sites there. So, when we click on Social Networking, it should show many other options below it that allow you to individually choose if you want to allow Facebook and Linkedin, but uncheck X and Instagram.

Also, there should be a list somewhere of a description of each category so we know what might exist within that category. Either a KB article or an information button next to each category that you can click on to see the info.
