security roles in succession planning

Summary

how to view all successors by the manager

Content

Hello,

we would like to know if is it possible to create the following custome role: a manager that can view into a succession plan all the successors even if they are not his direct report.

The issue that i have at the moment is that the standard role of line manager do not access to the succession plan, so i create a custome role where i put all the duty and privilege of succession plan. so now my scenario and question are two:

1) if i associate this custome role + the standard role of manager the user can view the succession plan and the successor (only his direct report). But if i use only the custome role i can see the plan but no one inside it and i cannot add them. do you know wich are the security policy in order to use only the custome role?
