How to create regions and zones in OpenStack Swift? [on hold]

I want to add drives from different geographical locations. Like this:

swift-ring-builder object.builder add --region USA-east --zone New_York --ip {ip} --port 6000 --device d1 --weight 100
swift-ring-builder object.builder add --region USA-west --zone San_Francisco --ip {ip} --port 6000 --device d1 --weight 100
swift-ring-builder object.builder add --region Europe --zone France --ip {ip} --port 6000 --device d1 --weight 100

Do I need to create these regions and zones before using them?
