Names of the product list types that are updated or removed
controller/common/product/import/csv/processor/product/listtypes = Array (  => default )
Aimeos offers associated items like "bought together" products that are automatically generated by other job controllers. These relations shouldn't normally be overwritten or deleted by default during the import and this confiuration option enables you to specify the list types that should be updated or removed if not available in the import file.
Contrary, if you don't generate any relations automatically in the shop and want to import those relations too, you can set the option to null to update all associated items.
