Need Payment Accounted Amount in 'Payment' Transaction Model Object

We have a requirement to detect the accounted payments above the USD.100,000. So, in this case, payment may happen in any currency but we want to consider the accounted amount (Ledger currency, in our case USD). But we can see only the payment amount showing in the entered currency.

We request that if we get the accounted amount as part of the "Payment" transaction model object, that will help us get the Payment amount in ledger currency (USD).
