Our teller software, Vertex, allows us to have two separate fields. The remitter, which appears on the check and the transactor, the individual who is purchasing the check. The transactor information is captured for MIL, the remitter information prints out on the check.
This is convenient when someone owns a business and they want their business name to appear on the check as the remitter, but the business is not really purchasing the check. The business name would appear on the check as the remitter, the teller would take an option to also have a "transactor" and collect information on the individual for the MIL.
