How to make a product category system in Modx, but not through TV?

Question

MODX

I want to create a category system on my site. One product can be in several categories. For example, the product "Table L456" is available in the categories "Home Furniture", "Office Furniture", "Computer Tables".
I tried to make categories through TV (TV - checkboxes. And the values ​​​​of this TV are resources that are responsible for the categories of goods. That is, I can put the checkbox "Home Furniture", "Office Furniture", "Computer Desks" in the product. And he will belong to these categories). Not a bad option. But I want something else.
I've tried using symbolic links. But then you need to copy all the TV of the product (price, picture ...). And if you add this symlink to the cart through ShopKeeper, then the symlink and the original product will be different products.

Go to miniShop2, where it is implemented out of the box.
