I know what you are talking about but i suspect that this is more like territorial behavior and probably only occurs in male animals.
You might get them to go in the same place a couple times but they will eventually want to poo on new territory. And then how would you correct that behavior? Usually when you tell a snake "No" they respond with a resounding "Yes!!!" I wouldn't be surprised if you did it though but it would have to be a pretty unique individual.
