PeopleSoft 9.2 - Payroll For N/A

Have a deduction for union dues that is 1.3% of gross withheld biweekly. Any way to set a min & a max? We cannot withhold less than $9.00 or more than $17.00. Is there a way to set a min and a max around a deduction? I have looked everywhere and don't see a way to do this. Right now Payroll has to manually review every deduction amount every pay to identify anything outside of the min/max and then go adjust all the amounts....
