On my D1 flights, the pursers were very emphatic that if you had pre-ordered a meal, you could change your mind and switch to one of the other (regular) choices. This surprised me, because IME with SQ's Book the Cook (J or F), you can't switch meals unless there are leftovers, which apparently doesn't happen often.
