python - How to route a chain of tasks to a specific queue in celery?

When I route a task to a particular queue it works:

task.apply_async(queue='beetroot')

But if I create a chain:

chain = task | task

And then I write

chain.apply_async(queue='beetroot')

It seems to ignore the queue keyword and assigns to the default 'celery' queue.

It would be nice if celery supported routing in chains - all tasks executed sequentially in the same queue.

I do it like this:

subtask = task.s(*myargs, **mykwargs).set(queue=myqueue)
mychain = celery.chain(subtask, subtask2, ...)
mychain.apply_async()
