Want best times in stunt runner? Doing great until you accidentally fall on Course 5? Say goodbye to S+ rank. Do it over and over and over again from the very beginning. Annoying isn't it? Why not for solo instances, just redo the current course or all courses with a push of a button, instead of restarting the whole room by starting another private instance, going through the "lobby" and entering into the private instance again (Takes about 2 minutes. Mess up in 25 seconds on the course later? Do the 2 minutes again!). Seriously. Many stunt runner soloists would LOVE this. Add it in.
