lookaAt interval?

is there something like a lookAt interval in Panda?
I guess I could just use lookAt(), store the rotation, undo the rotation and start a Hpr interval from the value I got, but maybe theres a nicer way. Plus this wont work if the targtet position will change while the interval is running (in that case I could do the same things in a task, but spaming lookAt() each frame and then another setHpr() is maybe unnecessary).

No, there’s nothing built-in to Panda to do this automatically. What you describe sounds like a reasonable solution.
