Integration of leftovers in Opencart?

Question

opencart

There are leftover goods in exel. There is a program that changes the balances on the site by product SKUs. How to score (change) balances for products that have options? Options: color, size. the program involves changing the balance if there is a separate product card with an article (for example: Bernd black T-shirt XXL). And I would like the product card to be ONE - a branded T-shirt, here the buyer can check the color and size of the available goods. They tell me that this is not possible, because. Each product must have a separate card with an article number to automatically change the balance, which the buyer must switch to in order to put it in the basket. In this case, you need to start 20 pages with colors and sizes for one product .... Are there any solutions for Opencart to be like on all decent sites?

Answer 1

You need to add SKUs for options and update balances for each option.
+ you will need related options as far as I understand

Answer 2

Of course, there is such an implementation. Here is an example HERE
there is a loader that forms one product card from several goods of the same type.
