@royce - Welcome to the Seller Community, and kudos on your first post! 👏

As for your question, we don't currently offer this functionality, but you do have a couple options: 

1. Issue a 100% discounts for an item to comp it.

2. Manually adjust the amount of stars that a person has. You can find more details on that process here.

Hope this helps!
