Can a I have a brachioplasty and mastopexy done together?

I am going to have a bilateral brachioplasty done in a few days. Since I have excess skin next to my breasts and in the underarm area, I wanted to know if at the moment the doctor is performing the surgery and he sees my excess skin on the side and that connects to the breast, can he make a decision right there and do the mastopexy?
