Need opencart expert

Hello I have an Opencart shop with a custom importmodule provided by my product deliverer... I use English as backoffice language and Danish as frontend language. The import module imports the products and categories to the language used in the backoffice which is English. I would like it to import product descriptions to both Danish and English and the category names to English only. I added the cart file from the stockmanager. I can choose if i want to use 1 language or the other but I dont know how to import descriptions to both lamguages and categories to 1 language.
