Question about posting items in the blog and filling the Required Product fields

Let's say I want to post an asset to the blog. And the item requires other third-party products.
I know when we post items to the blog there are two fields that let you enter the Required Product Name and the Required Product URL. My question is: what should we do when the asset requires MORE THAN ONE extra product?

Here's how the blog post form looks like:

See, there's only one field for Product Name and one for URL.

For example, consider this blog post here: https://zonegfx.com/shin-yeon-hd-for-genesis-8-female/

Scroll down a little bit and you'll see the required products:

There are two required products listed. Each one is in a different line and with individual clickable links.

So, considering how the blog submission form is presented to us, how did the user manage to format his post that way? If there was only one product, the answer would have been obvious: just enter the product name, then the product URL and done! But there are 2 products listed there, so how could he do that?
