AR Bank stmt processing

We are using AR_BNKSTMT process to load deposits (checks/AVH/WIR) from Bank into AR module. We deposit multiple checks in one deposits which in turn will create one payment id in AR. the issue we have is at the time of appllying payments where the AR group who is applying payment dont know who is the customer against each check.

Question is:

1. Can we stop cretion of deposit just for checks.? We still want to create deposit through AR_BNKSTMT for WIR and ACh deposits.

2. The above change is required only for one bank and not for all the banks.
