Puerto Rico Withholding Tax Exemption

Within 300CRE, has anyone been able to successfully implement Puerto Rico withholding taxes when a Withholding Exemption Certificate with Form 499R-4.1 is claimed by the employee?  I am wondering if the PRSWH tax formulas in Sage need updating to account for the very specific anomaly but yet still common PR tax law.

The current PRSWH tables and formulas are working correctly -- but when this withholding exemption is claimed, there doesn't seem to be a way to handle it.

In short, young individuals who are between the ages of 16 and 26 can claim an exemption of Dept. of Treasury withholding taxes on the first $40,000 in wages.

I am a not finding a way to implement this very specific exemption natively and automatically.   I have solicited the help of my Sage Consultant who is out of ideas and wonders if Sage should update the formulas themselves to account for this exemption.

I wanted to reach out to see if anyone has any experience with this exemption?
