Different column translation on variant

Setting a different translation on a table/subject variant requires checking the Translate column on the Subject>Variant>Settings.

Now that I'm using a variant with different translation, I notice that the column translation actually should be different depending on the variant.

For instance, take a product and an order table with a cross-table order_product. When order_product is linked to order, I put the translation “Product”, while seen from the product side I'll call it “Order”. This on subject/variant level. Let's say I have a column number_of_product. From the direction or order this indicates the number of this particular product. Translation could be “Aantal”. From the direction of product I want a different translation to indicate that this column says something about product and not order, such as "Aantal van product”.

How do I create a different translation for a column, depending on the variant that is shown?
