Is there a way to provide more customization for user roles? I believe I need something beyond page level permissions and user/designer roles. For example, I have a group of 6 people: 

-I want NONE of them to have designer capabilities. So, 6 "users".

-I want ALL of them to be able to see all the same forms/tables.

-However, I only want TWO of them to be able to edit records in the table. (to update information as we receive it)

Any help?
