Proxima Payment terms with multiple due dates

I have a vendor whose payment terms are:

For an example invoice dated 7/01/2022, with a total due of 1,200.00, the payments are due:

1st Payment due on 9/25/2022 for one-third of the total or 300.00

2nd Payment due on 10/25/2022 for one-third of the total or 300.00

3rd Payment due on 11/25/2022 for the final third of the total or 300.00

I have encountered these terms, in other applications called Multi Term PROX. The terms include a number of months to add tot he Invoice Date, then the day of the month Due.

PROX 2, 25 would indicate any shipment in July would be payable on the 25th of the 2nd Proximate month, on the 25th day.

Multiple PROX would take the Invoice Total divided by the number of Payments and assign due dates to each partial payment, as follows:

PO Amount $1,200.00 shipped on 7/1/2022 under Multiple (in this example) 3 PROX Payment Terms of 2, 25; 3, 25; 4, 25 would become due:

$ 400.00 on 9/25

$400.00 on 10/25

and $400 on 11/25.

I have also encountered functionality called Payment Schedules which provide equivalent functionality.

I haven't encountered a way to set up Multi Payment PROX Terms, Payment Schedules or anything functionally similar in Quickbooks.

Please let me know if they do exist and where I would find instructions for setup.
