iExpense - Processing CC transactions for Inactive employees

Need help on how to process CC transactions for Inactive employees".

Scenario is:

We receive CC transactions for an employee who has been end dated. We do not have supervisor hierarchy in our system. I am aware that the Credit Card Inactive Employees report uses supervisor hierarchy to send the notifications to the supervisor so he/she can re assign it to someone else.

We created a custom report to identify Inactive employees. Now, how do we get these CC transactions assigned or delegated/assigned to somebody else, so that the expense report can be created for these transactions.

Thanks
