Making bill payments by BACS or Direct Debit NOT a check number

I am trying to make bill payments to multiple vendors using the "Pay Bills" screen.

However, these payments are made by BACS (bank transfer) not check.  Unfortunately, it appears that Netsuite will only allow us to make payments by check and auto assigns the next cheque number.  The means we need to go back and manually change the cheque number on the payment to be "BACS" or "Debit" or whatever.

Does anyone have a workaround for this?  Is there a way of telling Netsuite that we're not making payments by cheques but my another method?

Thanks
