Quesions related to Expense Audit Functionality

Summary:

We are able to see inactivated/termed employees in the 'Assign to Expense Auditor' page. How can we remove these terminated employees from the list?

Does the 'Assign to Expense Auditor' page display all the direct reports of the person assigning the expense report? Do people without Expense auditor role also get displayed in this list?

Once an auditor is assigned to an expense report by clicking on the 'Assign' button, can a notifcation be sent to the auditor that an expense report has been assigned to him/her for audit? Or, do they have to come to the Manage Expense Reports page and look for expense reports assigned to him/her?
