Traffic through active connections after deny in address-list

I my Cisco ASA I filter incoming traffic by using access-lists. I have noticed that if I change the action on entry in the access-list from permit to deny, traffic still flows through connections that were active when I did the change. It seems that only new connections will be denied. To stop the traffic in active connections I have do run a "clear conn address x.x.x.x".

What I want is that all traffic specified in the access-list is stopped immediately when changing from permit to deny, without having to run the clear conn manually.

Any tips on this?

You won't be able to achieve this as far as I am aware. This is due to the way the ASA handles it's traffic to make it a lot more efficient. You could of course adjust the timeout values on TCP connections for example so the sessions were torn down quicker.
