Is it possible to assign message from a queue to specific listening service

Hi,
New to Nameko, I have two exchanges running within one rabbitmq node. I want to assign the message from a queue to specific exchange. Is there a way to do that?
I am using clusterrpcproxy and it takes only AMQP_URI in its configurations, It randomly assigns the message to any of the two listening service(exchange).

with ClusterRpcProxy({'AMQP_URI': AMQP_URI}) as cluster_rpc:
       cluster_rpc.some_service.some_function()
