Can't we assign other country employee as a line manager for different country employee.

Summary:

Example: there is one employee from India and there is no active line manager for that employee so as per business requirement HR needs to assign different country like Portugal employee as a line manager for India employee but when HR tries to change the line manager, they are unable to find the portugal employee. here I would want to know the correct behaviour here.
