Kohana, categories and multicategories for products, product binding, how to untie?

Question

Kohana

Hello , a question arose about categories and multicategories, the programmer made multicategories, I add one product, it fits another 5 categories, put down another 5 categories for the product beyond the main one, then if I add the product to the basket from additional categories, then the product link goes to the main first category to which the product was added, it turns out that it is not clear from which category the order was made, then I make an order and the product goes to the admin panel in new orders, there the link of the product goes to the first category that was put in the product, the question is how to do this so that the category of the product is transferred, that is, where the product was ordered so that the path there and if you click on the product, so that it is clear from which category the product was taken, otherwise it’s not clear right now.
How best to do, advise, throw ideas.
