Report to show all future approvers

Content

Hi, 

Does anyone know of a report or way to query, all future approvers in an approval chain for notifications. For example, next approver is person x, then once they have approved it would go to person y, then thereafter person z etc

I can find reports that will show person x, but we want to be able to see how many notifications are lined up to reach person y and person z. This is so that if person y or person z leaves, we want to find out which transactions will come to a halt as that person is no longer present.
