Security for New Constituency

I created a new constituency. I am in Security trying to give users groups access to the constituency. I want the users groups to have the same access they have to most of the other constituencies. There is no special security with the new group. Most of the existing users groups should access to these records. 

Do I have to go through each security object in each user group to determine the access to  Add, Edit , Delete and View?  This seems to be a very arduous task when adding a constituency. 

Please let me know if you have suggestion on how to address giving many users group access to a new constituency.
