Employee Reimbursements thru Payroll

Does anyone know how to set up JDE E1 so you can pay employees for expense reimbursements through Payroll instead of AP?  We currently give employees separate AP checks for these reimbursements and would like to create the AP vouchers but have them paid to employees on their regular pay checks.  Would love to hear from someone who has done this to help me figure out how to set it up.  We are currently upgrading to JDE 9.0.

Thanks!!
