Exclude select products from sale

Hi, I have the pro version of your plugin and it’s great. I mainly do sales in ‘category pricing’ or ‘advanced category pricing’. There are a couple products I want to exclude from a sale but I need to keep them in multiple categories so I don’t want to move them out of the categories that are on sale. Is there code I can add to functions.php that will allow me to exclude a few products based on the product ID? If so, is it possible to provide that code? Thank you!
