### define swift replica count by region?

Is there a way to specifically define how many replicas a region will contain? For example, assume 10 nodes each in Los Angeles, Dallas, and New York, for a total of 30 storage nodes. How might we accomplish the following with storage policies?

Policy 1
Dallas: 2 replicas
Los Angeles: 1 replica
New York: 1 replica

Policy 2
Dallas: 2 replicas
Los Angeles: 2 replicas

For policy 1 could we configure the object ring to have 4 replicas, then the 10 nodes each in Los Angeles & New York would have 1 zone, and Dallas would have 2? Would swift distribute a partition across the 4 zones? In this scenario the zones no longer reflect the pyhsical environment which seems to contradict the deployment guides.
