I have product tag archive pages that show on the front end; I'd like to only show the variation that matches that product tag. For example, if the product tag is 'Summer' and there is a variable product that has 'Spring', 'Summer', 'Autumn' and 'Winter' variations, I want the Summer thumbnail and link to show in the loop on the /product-tag/summer/ page.
I'm assuming this will need to be done 'manually' with php by altering the query for that tag page, since there is no native support for adding tags to individual variations. Is this possible?
