Reminder email notifications to people who are next on the approval workflow

Summary:

Email notifications to people who are next on the approval workflow if they haven't approved or denied the transaction

Content (required):

Is it possible to automatically send notification to people who are next on the approval workflow if they haven't approved something for a few days?

For example an Invoice Payment was submitted through the approval workflow by Alice. Now it is waiting for approval from John. John hasn't approved the invoice after a week, is there a way for the system to send a second notification (reminder) email to John because he hasn't review the transaction?

Thank you.
