Has anyone created their own custom solution for Involuntary Garnishment

Summary: Involuntary Garnishment is not considering after tax medical premiums

Content (please ensure you mask any confidential information): We currently have a SR open because the Garnishment element is only including pretax medical deduction when determining disposable earnings. State of Colorado does recognize after tax deductions for medical premiums. Oracle's response is "There is not an out of the box solution. You would have to work with your implementation partner on a custom solution. Or you can calculate the correct deduction amount manually each pay period and use the Statutory Rules Override Amount. Care should be used with this override as it bypasses all the legislative rules and deducts the amount entered".
