Hi,
Could you get available to re-define pre-set primary roles? I'm about a 'moderator' at first.
Moderator role provides almost full access to all data which had not to be visible for outer moderators (fans, super users). Sure I can provide them with moderator permissions using a custom role.
BUT:

1. They do not have a "Moderator" title visible for others (I can just enter a custom user title to do that)
   
2. I cannot assign any topic to them. It is possible to assign topics only for those who has Primary role = Moderator etc.
   

Actually, it is a deal of internal discussion - to decide which scope of permissions should moderator have. So I think it would be correct to enable an ability to re-define primary roles according to the specific community vision.
