Final Fantasy Hacktics

So i created a new Iaido for a new katana i wanted to create... I wanted to have a Iaido do Celestial Stasis. (Im working in WotL)
I replaced the skill "bind/00C1" with Iaido ability that I wanted, made its formula that of the "Masamune" and put "00C1" into the samurai skill set.
I even messed with the animations tab on FFTP to match the other Iaidos, so it would seem legit.
When i get into battle and try to use it the ability, "00C1" says "Genji Helm" instead of the katana I made. I cant figure out what i need to change in order for it to reference my new Katana and not the "Genji Helm"... or if new Iaido are even possible!
Any ideas?

Anyone??
