Need to skip a step in expense report creation using personization

We are loading Mastercard credit card (company paid) transactions into iExpense.  For credit card users, the step 4 "Receipt Based Expenses" is not part of our business process and need to disable it.  Is there a way to bypass this step so that the user does not see it?  Can a personalization be done to the "Next" button from step 3 to go directly to Step 5?  I would appreciate some tips on how to do this since I am not familiar with creating personalizations even though I have read through the manual.  Thanks!
