When a guest or Property Manager (PM) submits a request to change their reservation, a temporary block will be placed in Hostfully PMP. If the PM or guest does not respond to the request, the temporary block will remain in PMP. I want to be able to submit, manage and withdraw Airbnb trip change requests in Hostfully; or make trip change requests auto expire after 24 hours, for example, so I don't have to withdraw the request from Airbnb to remove the block.
