Union Shop Steward

SUGGESTED

Wondering how people set up their Union Payroll for a Shop Steward.  I have all Union deductions/fringes set up and Pay Tables for Union Wages but I am wondering about how to set up the additional amount when the employee is a Shop Steward.  Was thinking about doing new "class" for each needed but was wondering if there was an easier way.  Has anyone figured out this issue?
