There are currently no mechanisms in place that default or require a particular due date to be set on new loan accounts. We have considered this in the past and may take another look at it in the future in light of these types of regulatory changes, but for now this must be a procedural change for your loan officers.
NOTE: This is different for online credit cards, however. Since the due date on credit cards is determined by the loan category configuration, loan officers do not need to specify a due date on new accounts.
