How to get UFW to read current iptables rules after modification? (Ubuntu)

I am adding a chain using iptables: iptables -N ETDROP When I reboot, this is lost. I read of many ways to make iptables rules permanent... however You must remember, I am using UFW and UFW has this job of remembering your rules. So the question is, how do I get UFW to realize that a new rule has just been added directly by iptables? I tried ufw reload but no cookie.
