Hello, We are working on a workflow to cancel in progress rolling updates for the resource OS::Heat::AutoScalingGroup When we run the command `openstack stack cancel <stack-id> it cancels the Heat stack update, but the Auto-Scaling group finishes updating all VMs in the group. We need a way to either rollback or completely cancel the Auto Scaling Group update and not replace any additional VMs. Any help would be appreciated. Devin
