Can PO Approval Time out to be Approved Automatically?

Hi Everyone,

we are using the feature of time out inside PO approval . And when using this feature the system send 3 notification to the approver:

1- original notification.

2- first reminder.

3- final reminder.

then it goes to the next approver and so on. if this is the last approver in the hierarchy the system return the PO back to the buyer with incomplete status.

My Question here: can be the PO be automatically approved instead of being incomplete status?
