CSV Import combinations with shared images

[InuP]

Is there an easy way to do this? I have close to 3k products to import.

Here is the issue - I have clothing with two attributes, Size and Color. The product images are only different for Color. For example Red Small, Red Medium, Red Large combinations all have the same image, while Black Small, Black Medium, etc would all have the same image. So with something like 10 colors and 7 sizes per product, that's 70 combinations but only 10 images needed.

When I do a csv import and enter the image URL for all 70 products, Prestashop duplicates each image 7 times and then ALL of these are shown on the product page.

If I do the csv import and only include each image once (on the first size for each color), then all the other sizes do not have associated images. And I would have to manually select the image for all the other combinations in the admin panel, which is massively slow and clunky.

Ideally I'd like to link an image to ONLY the color attribute for each product, but I haven't been able to find an addon that does this.
