In EBS 12.2.11 iExpense, is there a way to prevent use of the Cash and Other Expenses step?

In EBS 12.2.11 iExpense, is there an easy way to personalize/customize the business credit card template so that the user cannot make entries in Cash and Other Expenses (step 4) ? We only want the user to expense items from the pre-loaded Chase transaction and not be able to enter expenses manually for personal charges. For personal credit card purchases they can use a reimbursable template.
