3818518 - Is it possible to assign a default expense type when the Personal Expense (do not reimburse) checkbox is marked/checked by the user?

I would like to know if there is a way to default the expense type to 'Personal Expense' when the checkbox 'Personal Expense (do not reimburse)' is marked by the user. We have an additional approver in our workflow in which the expense report is routed to him whenever a user has an expense marked as Personal but the selected expense type is not 'Personal Expense'. I would like this approver to be skipped for personal expenses.

Admin wants to have the expense type field to automatically update to Personal Expense when the Personal Expense checkbox is checked by the user so they can force their users to use Personal Expense for personal expenses instead of using other expense types. This is so the expense will no longer route to our additional approver (CFO) if the expense is personal. , KBA , CON-CA-ADM , Administration , Problem
