Payment Approval for payment amount grouped by the Supplier, Not the Payment Batch

Summary:

Currently, payment approvals are triggered based on the payment batch, and one email is sent to the approver on a payment batch basis. The business requirement here is to trigger payment approval based on the total invoice amount grouped by the supplier. Below is an example.

Below are the suppliers selected in the payment batch.

INV1-ABC Supplier Rs. 2000

INV2-ABC Supplier Rs. 5000

INV3-XYZ Supplier: Rs. 3000

The expectation here is that a payment approval email needs to be triggered for the ABC Supplier invoice amount payment of Rs. 7000, which consists of INV1 and INV2.

Is this achievable through the Batch Payment Approval BPM Task?
