Kong CloudFormation - Concurrent Migrations

Hi, we are using the provided Kong Cloudformation template to bring up multiple Kong instances for a Kong - Cassandra setup. I have found that if I set kong migrations = true, and set Desired = 2, I will have the first instance run successfully, but the second instance will throw an error due to what seems to be concurrent Kong Migrations. Is there a way we are supposed to be using the template to ensure migrations occur on a single node, or somehow occur on each node in a sequential fashion?
