How to make a queue manager default in a cluster

Question

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

Adding to T.Rob's suggestions here are couple of options you could take a look at:

1. Disable put on cluster queue instances in london and paris. So the messages will be distributed between newyork and tokyo.

2. Write a cluster workload balancing exit that will skip putting messages to cluster queues in london and paris and puts messages only to cluster queue instances in newyork and tokyo.

See Writing and compiling cluster workload exits from the MQ 7 Documentation.
