How to add a validation on Quick add?

Hi Community!

As per current design the standard 'Quick Add' feature is available for users to add parts to LIG directly. Business wants to add validation so that a specific part when searched through 'Quick Add', appears in the search result but can't be added to LIG if the validation fails.

We need that part to be showing in the result, but there should be a error message in Quick add itself.

Search the part and Select it + Click OK = Error message on the top Box.

Thanks for your Help!
