Hi,
Actually I am facing the same.
We have about 4000 products.
Currently we are linking the products in the metafield and then add the section into the product page template. See example below.
I am still looking for a better way to automate this.
I was thinking that maybe this could be done automatically based on tittles? Because the tittles are mostly the same only to have an color added to it. Or something else added to it.
