This is possible by using a Receiver object which supports batch operations. Refer this sample which showcases how to get this object for a subscription.

To guarantee you get batches of messages, you have to set the prefetch argument of get_receiver() to your batch size and consequently the max_batch_size argument of fetch_next() to the same.
