Is it possible to move / merge messages between RabbitMQ queues?

Question

I want to know if it is possible to move / merge messages from one queue to another. For instance:

main-queue contains messages ['cat-1','cat-2','cat-3','cat-4','dog-1','dog-2','cat-5']

dog-queue contains messages ['dog-1, dog-2, dog-3, dog-4]

So, the question is (if both queues are in the same cluster, vhost), can I move messages from dog-queueto main-queueusing rabbitmqctl?

So in the end I want to get something like:

Perfectly:

main-queue: ['cat-1','cat-2','cat-3','cat-4','dog-1','dog-2','cat-5', dog-3, dog-4]

But this is also normal:

main-queue: ['cat-1','cat-2','cat-3','cat-4','dog-1','dog-2','cat-5', 'dog-1, dog-2, dog-3, dog-4]
