subscription billing- create an AR Invoice with past date according to the 'Interface Date'

Hi,

We have a case of Contract Usage billing periods on 1st of the month to the end of the month while the 'Interface Date' is also the last day of the month.
We want the AR Trx Date to be also the last day of the month, even if the billing line is sent to the AR only a few days later (we are waiting for the usage qty to be calculated and updated).
As in the example attached, the billing period is 1/1/25 till 1/31/25 and the interface date is at the end of the period at 1/31/25. We update the usage qty on 2/1/25 and send the billing line to AR. The AR TRX_DATE was created with the the date of 2/1/25 and not the interface date of the billing line.
