Is there a pet ability toggle macro?

i.e. something like:

/script petautocasttoggle Seduction

It would be handy to tell my succubus via a macro when I want seduction chain cast and when I want it off so I can just use her regular attacks.

There is API function TogglePetAutocast(index) where index is number of pet ability. So if seduction is pet's 5th ability you can use /script TogglePetAutocast(5);

Another solution is to use addon Zorlen (http://addons.us.to/addon/zorlen-0). It provides various useful function, including function to set pet action autocasts. Example:
/script Zorlen_TogglePetSpellAutocast("Seduction", "on");

Thanks, Ill give it a go. : )
