specific skin ID block sell

Can you add the the function of selling items of a specific skin ID, and Skin id Blacklist function? Blacklist makes it impossible to sell items of a particular Skin. Even if the short name is the same, depending on the skin, there may be items that the players do not want to sell. In other plugins, Items with a specific skin ID have the ability to give additional figures that like the amount of damage and defense. So even if a specific Skin is the same short name, it's a good feature for me to have it sold at a different price!
