There's no functionality for that in CB. CB Moderators have global permissions for a lot of plugins. As for editing users it is true they can't edit the profile of someone above them, but that won't stop several other usages like modifying CB Activity posts, deleting CB Gallery entries, etc.. they'll have full moderator permissions for those. I suppose your ACL would be setup as follows though.
Registered
- County 1 (assign members to this)
- - Coordinator
- County 2
- - Coordinator
Then for CB Moderators you'd create a view access level that included County 1 and County 2 Coordinator usergroups. Then set Moderator View Access Level within CB > Configuration > Moderation to your view access level.
