VRBO spot rates pushing - what is overrided

wondering what happens when I push spot rates onto dates that are already booked in vrbo?

I'm guessing the api blindly pushes whatever I tell it to push, which probably isn't a problem but implies that I need to keep my own records about each nights pricing at the time of booking in order to track what guests paid for. Within VRBO's platform the per night granular rates get lost after booking and all I know is the total booking.

UPDATE - I tried unclicking the include rates box and it appears nothing got pushed.

It doesn't error if that's what you're concerned with. If you're wondering if it will maintain the old rate (prior to booking) the answer is no. It will update. Keep in mind that the booking could cancel and be re-booked by someone new at any time, so you want to continue maintaining rates.
