SQUIDGUARD:DIFFERENT DNS SERVER FOR DIFFERENT GROUP ACL'S

[mendilli]

I am using squidguard and it works flawlessly, my target is to achive assigning different dns servers based on squidguard groups.for example

I have a group acl which represents limited users and another group acl which represents unlimited users

I want to make the limited group to use x.x.x.x dns server and unlimited group to use y.y.y.y dns server.

is that possible in squidguard?

I need this because our laws say that we have to block web pages containing criminal activities and MY ISP provides this over their dns automatically, but at the same time my company works on criminal activity studies so some users should be out of this restrictions(unlimited users)
