Transfer Permissions from Default Cerberus Group to Custom Cerberus Groups

I had configured a default Cerberus group which disabled users by default and didn’t allow any logins.  This group was selected as the default group and directory mapping for AD Users.  I then customized the defaults using “AD User Customization”.  I mapped my AD groups that I want to have access to the Cerberus groups I created.  I thought that these custom mappings would overwrite the defaults of the "no access" group.  Reading more into the documentation, it seems like the permissions don’t get passed between the "no access" group and the other groups, only the virtual directories are passed. 

It would be nice if the permissions could be passed between Cerberus groups so that I could use a default Cerberus group to restrict access fully to all users by default.  Then, if I create a custom AD group to Cerberus group mapping, users in those mappings would have access that overwrites the default "no access" group.
