zenoss batch add nested locations

Hi,

Im looking at ways i can batch add locations under existing organizers.

For insance
i have under locations
/cityA/
/cityB/

How would i add
/cityA/townA
to an existing cityA using batchaddlocations.py script below...if i try to prefix cityA to name it fails.

#!/usr/bin/env python
import Globals
from transaction import commit
from Products.ZenUtils.ZenScriptBase import ZenScriptBase
dmd = ZenScriptBase(connect=True).dmd

file = open('/home/zenoss/provisioning/location.txt', 'r')
for line in file:
line = line.rstrip()
name, address = line.split('\t')
dmd.Locations.manage_addOrganizer(name)
location = getattr(dmd.Locations, name)
location.address = address

commit()
file.close()
