Can we add full directories and sub-directories as exclusions?

I want to add my anti-virus program to a firewall exclusions list, I’m always having intermittent problems with it’s online updates while I’m gaming, with the firewall running. Even if this isn’t my problem, allowing me to exclude the whole directory would be an easy way to void that out. I also could exclude the game directory for other testing purpouses. Is there any way we can get this option added to the v2.4 and/or v3.0 Firewall Suites =).
