Hello Amos,
Sorry, I am not sure I follow you correctly. Could you please clarify your request more detailed by providing an example?
In case you need to edit a booking after it is made, you can easily do it within the 3.8.0 Hotel Booking version (video tutorial).
As for synchronization, once accommodation is booked, it also becomes unavailable on OTA. Here is an article with more details.
Best Regards,
M. Evans
