Connection queuing in FT pool members

I have a VS with no http profile attached. 1 pool and 2 pool members A and B. A has priority 1 and becomes active member and B has priority 0 and becomes passive member. All the traffic goes to member A. ICMP help monitor is configured with interval 2 seconds and timeout 7 seconds. For example now the member A stopped responding But F5 will mark member A down after 7 seconds and after that passive member B will come up and start responding to traffic. But in between these 7 seconds all the new requests will lost as VS was sending traffic to A which was not responding and B was in passive state and VS was not sending traffic to B. What i want is that F5 keep new connections in queue for 7 seconds and send it to member B when VS mark member A down and start sending traffic to member B.
