Crediting transaction with invoicing and accounting rules.

Hello,

Is there anyway we can manually enter the duration when crediting a transaction with invoicing and accounting rules? This is a mandatory customer requirement.

EX : Customer entered a contract and an invoice is entered for 91000 on 01/01/2020 and the revenue is recognized daily till 31/03/2020. (1000 per day for 91 days). If the customer terminates the contract on 20/02/2020, the revenue that was to be recognized from that day to 31/03/2020 should be credited from the invoice amount since the customer cannot be charged furthermore due to regulations.
