I have 2 free nights rewards for hyatt and 40K points

Im trying to book a week long stay in orlando. For some reason when I click on redeem free nights, the reservation wants to try to use all points and tells me that I do not have enough points for the whole stay

If I click on free nights and choose hotel it will let me only book one night each with the free rewards, then I would have to book another reservation using my points for 3 nights which I will have enough

Is there a trick to book a week stay using 2 nights and points instead of making 3 different reservations?

I rem seeing something where you could pick the date of the week stay to use your rewards nights and points or choose to pay for nights

Or have to call customer service to book?
