hello dears,

Where do you want to add category names to products?
If in breadcrumbs, enable "Category breadcrumb enabled" in Catalog Settings.
If in URLs, set "Product URL structure type" to "Category/Product" value in Catalog Settings.
If in names, just change product names accordingly.

thanks alot :)
