Question about potty training commands

Nitty gritty question: when you are training potty habits and training to a potty command to try to get them to go on command, do you teach them a word for poo and a word for pee or are they both called potty (or whatever your euphemism of choice happens to be)? My dog seems to have learned the word potty and outside, but I think we are far from going on command at this point and Im wondering if I just made it more complex than necessary?
