The easy way / method to apply this policy?

Hi all,

Let's say i have 20 security zone and each security zone have zone-to-zone policy. Each security policy have around 300 policy. If want to add new policy let say block TCP_450 and need to apply at all the security policy zone-to-zone at the top of policy then how to do like that? If using global policy then i will read as last. If create a "apply-group policy" and bind it to security policy then it still read as last policy right?

Thanks and appreciate any feedback
