Prevent duplicate address objects on FortiOS

Anyone know of a way to PREVENT duplicate address objects from being created on FortiOS. 

Scenario: On a FGT, you create an address with the below:

config firewall address

edit h_1.2.3.4

set subnet 1.2.3.4 255.255.255.255

next

end

What i am looking for is a way to prevent another object from being created with the same subnet value, even if it has a different name. Lets say it warns you that an entry already exists.

Thanks.
