Payment Predictor Algorithms

We had a situation come to our attention today where one of our billing systems is sending the following invoice example

Invoice 123 line 1 $75 Document ABC
Invoice 123 line 2 $25 Document ABC

We receive payment on the 1st for $75 for invoice 123.  The AR Coordinator enters the deposit info, the reference info and the system builds the payment worksheet with both line items for invoice 123 and the AR Coordinator needs to unselect the line 2 so the payment is in balance, and can be posted.

Is there any way to automate this between payment loads and payment predictor using algorithms so that the system sees that there may be 2 lines for the invoice, but one matches 100% so therefore that line can be closed.
