Prevailing Wage Rates in Sage 100 Payroll

Is there anyone who uses Sage 100 payroll that has prevailing wage jobs that can have a brief discussion with me?  We currently use T-Sheets to accumulate time for our Traffic Control Flaggers which is imported into Sage's Timecard module. There is a lot of manipulation to adjust the various wage rates to properly pay an individual.  Could use some assistance.
