Ebay seller, how does one create these type of eBay multi-listings?

So go check out this listing: https://www.ebay.com/itm/184336753289

I see a lot of these.  A seller wants to sell a lot of games or manuals, broken out by item in a drop-down but it's just one listing.  I have a bunch of manuals I'd like to sell and I'd like to list them on eBay like this.

The problem is I've tapped around and my Google Fu isn't working.  Everything I find for "mutli-listings" seems to explain how to create variations, like color and size of clothing, or it talks about multi-quantity, same item sells.

How can I make one of these?  Thanks guys.

They're using the advanced listing tool with variations.

• Variations - Save time and money by listing multiple variations of your item in one multi-quantity, fixed price listing.
  • If you can't see the Variations section go to the Pricing section and select Edit. Set the Auction toggle to off and select Done. The Variations section will now appear above the Condition section

Well, I saw that, I messed around with it and it's asking to create attributes and I don't want to waste to much time on this.  I'm not that siked about making these listings but I'll see if I can find a video based off of these details and try again some other time,
