Pre-payment discount

[Richard365]

I am wanting to offer a current/confirmed booking a discount on the stay if payment is made to the me (the Host) prior to the end of the financial year and in advance of the actual stay.  This is for the purpose of meeting a revenue target for the current financial year.  The guest is happy to do this as they already have paid ABNB and are happy to authorise for the payment to be released to me (the Host).  However, I can not find a way to affect that payment and discount.  Is this possible?  How do I talk to ABNB to get assistance?

Sorry @Richard365 but this cannot be done.  Yes, the guest has paid in full but this money will only be released to you 24 hours after the guest checked in, no exceptions.
