Sophos Central Adjust Customer Role

I would like to create the customer role of an admin.
Policies should only apply to the assignment.
Only if I do this I can't add any peripheral devices as an exception.
The policies must also be able to be edite or i'm wrong. Is there a way to allow the devices with the policie assignment?
