If it doesn't violate eBay policy (sorry, I'm not familiar with the terminology you included), then you would use variations. Here's a link regarding variations:
eBay policy:
By using listings with variations, sellers can offer variations of the same product in a single listing.
Allowed
- Listings with variations can offer a choice of size, color, scent, quantity, or material as long as the items are otherwise the same
Restricted
- If all of the items in your listing have the same Item Condition, you can have variations for minor condition differences like the same book in Acceptable condition where one has a torn cover and one is an old library copy
- You can offer parts of a set if all of the individual components are correctly categorized, and your title applies to all of the variations
- You can offer minor variations to customize an item, like a computer with different memory options
Not allowed
- Selling different brands or models of an item in a single listing
- Offering a choice between two different items, such as a watch or pair of shoes
- Selling items that would have different item conditions, such as a new and a refurbished laptop, in the same listing
