default task to close a Project

We have a growing number of projects that should be closed or completed. 

These projects are getting old and the users may have moved on and the names of the people in the Project Manager role may not be active.

Is there a way to set a default task to close the project (as a reminder)?

It is the people in the project who should know when to close the Project and how to close it (suspend, cancel, complete, delete) it.
