Hi All,

We’re running Impulse v7.3.4 and Shopify Plus.

We use the Shopify Search and Discovery App for our search and related product areas and want to use it for complementary products.

For the most part, it works perfectly well.

We have some products that pair well with others but only a certain sizes fit (ie: medium). Customers routinely buy the wrong size and it ends up being returned/exchanged.

So, can I add only the relevant/correct size variant (using variant ID) as a complementary product? And if so, How?

Best wishes,
Anthony
