Routing traffic from F5 BigIP LB to both EC2 instances and Physical servers together

Is there a way to make physical F5 BigIP LB to route traffic to both EC2 instances(Autoscaling) and physical machines? I came across this article http://ift.tt/WiMaLx but it seems it is routing traffic to an entire AWS zone, not to a couple of EC2 instances behind a ELB.
