Is there a way to calculate a proporational discount if you partially pay a Vendor early on an AP Bill?

Bill #  on 6/01/21  2% Net 30  on a Bill amount of $50,000

Client pays half on 6/29/2021 $25,000 to capture partial discount

Full Discount is 50,000*.02 = $1,000

Partial Discount is 25,000*.02 = 500
