The short answer is NO
It has mentioned here and elsewhere, many of us booked multiple nights stays at ONE NIGHT Per Reservation, precisely to preserve the flexibility in situations like yours, plus other possible plan changes.
This is not Marriott alone, IHG and Hyatt and HH, all would let you book ahead, albeit you need to pay at the time of booking, at the old level. But if you need / want to change anything, the existing reservation is voided.
You can call to plead your case as miracles occasionally happen.
