How to keep listing images from changing automatically on other marketplace when I change them on US marketplace listing?

I´m trying to add new images to my product listing on US marketplace as we updated the product a little bit. But since it is linked with the other marketplace, then the images change on the listing there as well. I have separate inventory in Australia for this product and do not want to change the images there as I don´t sell there the updated product yet.

I have excluded this Australian listing from BIL price synchronisation, so the price doesn´t change automatically in Australia when I change it in US, but how do I exclude or unlink the listing from US marketplace, so I can edit the images also only on one of the marketplaces?
