How Do I Use the Append Modifier?
Our modifiers allow you to change the product data without the need to make changes in the data feed.
Specifically, the Append Modifier is a command that allows you to add elements to an existing list attribute or a new one created by another modifier.
For example, you can take specific pieces of text from one list, and add them to another to make it easier to filter on things like color, sizes or other tags available for products.
