There are different ways of looking at the "pooping" subject. "IF", you're going to train the bird to go in certain area's; it will take time to train. 1st you have to observe the bird's eating habit and note how long it take's for it to poop, on average. That is a MUST. If you teach a bird to hold it, until a given time and place; you are asking for health issue's to come. So, there is going to be vigilance, patience, treats, and all manner of extra effort required to start such a project.
