Report Filter for Current User to See Top-Line Manager's Entire Team?

Looking for something like...

Assigned to User > Is > Current user
Assigned to User > Reports to > Current user

...but will allow the logged-in user to see the data of everyone on their sales team (so essentially take the top-line manager above the user, and show them everyone in that person's down-line). 

Sales managers at my company want all of their subordinates to be able to see each other's stats in order to drive competition. Is there any way to accomplish this using standard report filters that doesn't involve me creating a custom report for every management team? Ideally something responsive so I can create one dashboard that works for all users.
