Nope. The shaper command will last for like, 10 rounds or so, carrying out their current orders of killing, and then the creations will go rogue, slaughtering EVERYTHING in sight, either instructed to or not.
Or more. Really, it depends on the kind of creations and the character. I mean, the character hasn't developed what is needed to keep creations under control for long periods of time. Which is why you can only shape seven, and you can't leave them behind in zones.
