Changing Summon/Stance phrases?

[senseichen]

Is there a way to change what your pets say when they're summoned, or orders to change stances?  I feel like there is, but I'm not having any luck finding it.

Is there? I didn't think so. I think that you can force them to emote with commands, or make a macro that both has them change stance and say or emote something as they do, but I didn't think there was a way to change their defaults. So I don't know if you can replace the defaults as much as add to them.
