LTM Local Traffic policy precedence in 11.5

Hi, I have a problem using LTM Policies with a virtual server having a default pool specified and a policy to send the traffic to another pool if condition is matched. So my question is: When adding a LTM policy with its set of rules - say forward to a specific pool for a specific http-uri - to a virtual server resources , is this policy has precedence on default pool ? Or do you need to specify NONE in default poll and create 2 sets of rules for each pool you want traffic to be sent? Running BIG-IP 5050 v 11.5.1

Thanks,
