Add Manual Retirement to Career Mode

Hey -- UFC career mode is fun, I like it. I think one (of a few) thing(s) that would really take it up an entire level in quality of life is to just allow me to retire when I want. My fighter is like 30-0, "GOAT" status, two division champion, everyone I'm fighting is old/rematches. If this was real life, he would definitely retire. I shouldn't have to wait until my longevity runs out, which could be in idk how many fights-I-don't-really-want-to-play.

Would also love some more training mini games such as speed bag, jump rope drills, shadow boxing or pad work.
