Updating Remittance Advise

Good afternoon, we are finally starting to make payment via ACH out of Sage 100 and as part of that we are planning on sending the Remittance Advice via email.  However, prior to doing so we would like to make a couple changes to the remittance advice.  Particularly the line on our Advice that lists the full bank account number for the Vendor.  We are not a big fan of this.  How do we go about updating what information is presented on the Remittance?  Is it a Crystal Report?  Thank you in advance!!
