Sage 300 Payroll, "Timecard exists" warning

When in the Payoll-->Employees screen, when accessing employee info, a warning popup appears:  "Warning Description: A Timecard, an Employee Timecard and/or a Manual Cheque exist for this Employee. Changes to the Employee may affect processing."

While it's not wrong--we have a number of employees that we've had to make payroll timecards for--it slows down the data entry process.  Is there a setting that can be tweaked so that this warning does NOT appear?

Many thanks!
