EX 9.2 Employee Bank Account Question

We are implementing 9.2 Expenses, and also have PeopleSoft HCM.  My question deals with the delivered Integration Broker message to bring employee bank account information from North American Payroll into the Expenses module.  Let's say most employees have more than one bank account in HCM.  For example, $100 of each pay is put into savings account A, while the balance of the pay goes into checking account B.  Here are the questions:

• Does the delivered message bring over both accounts?
• If so, which one is flagged as the default in Expenses?
• If only one is brought over, which one is it?
• What if the employee wants their expenses to go to a 3rd account?
