[cloudkitty] Instances billing based on tags

Folks, We have an AWS project and in a single project we run multiple customers so for billing we use tags. In short every vm instance has a tag (customer name) and that way we can produce bills for each customer. Recently I am playing with openstack cloudkitty and it works with standard cases like project based billing. But does it support tags based billing just similar to what i have explained in the above aws example?
