Restrict Position Hierarchy on Team Activity Center

Summary:

On the Team Activity Center page under the Position View, we have the Position hierarchy button which shows the Line Managers (LM) the position hierarchy both upwards and downwards. In this way, the logged in LM is able to see and edit the positions of his direct reports as well as the employee he is reporting to (LMs manager) and person above in the hierarchy. How can we restrict the LMs access to position hierarchy only to their direct reports?
