Indivual roles and group roles in power bi

Hi,

I have Managers and Employees in the organization where some group of employees falls under each manager.So i have employee column where i created RLS for each employee.so whenever an employee logs in he should see his own data.I donot have a columns to define managers.So is there a way that using that employee column and define multiple roles for each manager.or can anyone suggest me what is the procedure that when a manager logs in,he should see the data that belongs to summation of all employees that falls under that manager.

Thanks in advance,

Ash
