Actually that is exactly what the white list/black list does.   Depending on which one you are using you are either approving or denying the domains that you want or don't want, while all other domains are explicitly approved or denyed.  There is not a way to set a black list and a white list at the same time as it would be counter productive. 

If you are looking at User or device based filtering then we would recommend a product with Homecare such as the Archer C2300 or AX6000.  Homecare allows you to set user based restrictions.  These restrictions can be tied to all of the user's devices and is intially set by age apporiate content, but you can also add additional customer restirctions if you desire.
