Manager not able to approve timecard for all reportees down his line of command

Summary:

Any manager should be able to approve or view the timecard for his direct reportee or any employee down his line of command.
Example provided in attached document.

Currently, we cannot find any navigation or path to achieve this in HCM. We do not want notifications to be sent but in general, if and anytime a manager wants should be able to approve.

Example:  Dave Brydl’s time, absence and expenses can be approved by either Kathi Conser, Chelsea Graylin or Mark Weiss.  Once approved by Kathi, Chelsea and Mark can still access and view the status.  If Kathi is unable to approve for any reason, Chelsea and Mark can both access and approve the time without the need for delegation or proxy.
