How to update products in existing categories in wpallimport?

Question

WordPress

There is WPAllImport Pro in Wordpress. It is necessary to periodically update products through wpallimport. Products (4000) are already loaded with their categories (hierarchical). For example: Lingerie - tights and stockings - large size. But there are many "large size" categories. Next time I will need to update the products, there will be 4002 of them, for example. And the new products will have the same categories: Lingerie - tights and stockings - plus size. How to configure wpallimport so that new categories of Lingerie - tights and stockings - large size are not created, but goods are thrown specifically into these and the hierarchy is respected? And how to make sure that the new product falls into the right category "large size" if there are a lot of them?
