What happens if you use this feature and later go to remove an award night or two and the same time the paid rates for your nights have changed?

For example, Monday night $100, Tuesday night $120, Wednesday night $120, Thursday night 12K, all under the one reservation. If you later go to remove, say, the Thursday night entirely (i.e. now a three night stay) but Monday night is now $175, will Hyatt try to charge you the new higher rate, or will it remain?

Historically, if I'm not mistaken, if you were to otherwise do this on a full revenue reservation, Hyatt would re-price the whole reservation.
