Yes - but all you need to do is to enable ingress NetFlow on your northbound 
interfaces and ingress NetFlow on your southbound interfaces. 

But I strongly urge you to pay attention to your crossbound traffic, as well as 
ensure you have traceback to the relevant interfaces for outbound/crossbound 
traffic.  This means ingress NetFlow on all relevant interfaces.
