Payment Predictor to do adjustments for underpayments at item reference level ?

Has anyone used PeopleSoft Payment Predictor to handle over/under payments ? We are looking to write-off based on tolerances set up on the Receivable Options . But it is not working for multiple invoice references in a payment.

We tried DTL_TLR algorithm to use the tolerances set up in the Receivable options . But the tolerance amount/percentage it uses at the Total Payment Level .

We want the tolerance to be used at each item reference level.

Tolerance level at Options level is 20$ and 2%.

If i have a payment at 200$ and get $240 for Invoice A and B. Considering Invoice A get 20 $ over payment and B get 20$ over . Both of the overpayments needs to be written-off.
