Really NEED the ability to assign more than one supervisor to an employee
I know that we can assign an alternate supervisor to someone who already has the supervisor role, but this doesn't work in every situation. We need the ability to assign a multiple managers to the employee as each instance might be unique.
Creating Supervisor access using rules like TWP's Login Maintenance
It is difficult to maintain Roles in each user's profile. A configuration that is more rule based like TWP's Login Maintenance screen will be extremely beneficial especially for companies with large employee counts.
