I have a cluster named inventory with 4 queue managers defined london, paris, newyork, tokyo. If london and paris are the default queue managers which get messages, how can I make newyork and tokyo as default to receive and not allow clients to put messages on london and paris but they should still be in the cluster. can this be achieved with workload management ? 

If there are any other solutions please let me know. All this should be done without making any changes on the client side.

Thanks
