In addition to the standard product attributes, Magento 2 offers a functionality for adding a custom option. As an example of such a custom option, a personalized engraving with the name of the buyer on a ring can be specified.
Mass Product Actions provides the functionality to copy the existing custom option from any SKU to the selected products. Since the product may already have a custom option, our extension allows you to replace it with a new one or add a new one to the existing one.
