Payroll Deduction Frequency

Our company has office personnel on a semi-monthly pay cycle, and field employees on a weekly pay cycle.  In both cases, the employee's benefit deductions only come out of the last check of each month. 

Is there a way to tell Sage in the employee setup (or elsewhere) so that these deductions pre-populate ONLY on the last check of each month?  I know it's a long shot but thought it would be worth asking.
