Goal visibility of a Line or Matrix Manager to NON direct reports

Summary

What are the best options for a line or matrix manager to see the goals of all the employees below them in the hierarchy?

Hello,

We have line and matrix managers who can view their direct reports in their 'team' tab in Goals Management.  However, they'd like to see all employees within their managerial hierarchy (not just one level down).  Wondering how others are providing this, and if anyone knows if this is in the roadmap at all.

I know there is some capability in the Workforce Goals - Goal Status Overview Real Time subject area to include top level manager, etc. What other options have others pursued?
