Halp! I've threadjacked myself!

No, I guess there really isn't a way to copy except by using #secondaryeffect and #secondaryeffectalways, which isn't the same thing. HOWEVER, sometimes they overwrite the original #newweapon definitions for some reason, you might want to give it a try anyway. That happened when I tried to add a "stun" secondaryeffect to a new weapon I created. Good luck.
