Ecommerce / Collection Conditional Visibility: based on qty of options

Hi all! First time I’ve been here to ask a question,

I’m trying to set up some conditional visibility on links in a collection item.

In this example (the slider of products midway down the page) each product has options - buy the original piece of art, or just prints.

Once the original is sold, I’d like to be able to switch out the “original” button for a greyed out version “original - sold” but I only have options to set visibility based on overall quantity of the product, not the quantity of specific options.

Please could somebody help, is this possible to achieve in any other way?
