Let's say I want to create filters for the customer to filter out products when browsing. For example, lets say I want the filter option available to the customer to be "Franchise" or "Series" and it's a graded trading card slab. You have a graded card that belongs to a franchise or series "ABC" and it also belongs to franchise or series "XYZ" as well. Maybe XYZ is the sub category of ABC.
So if I set up variants and I create two entries for it, one being ABC and the other being XYZ, and it's a single item, well the problem I run into is that if I have the amount available as 1 for ABC and 0 for XYZ, it will show XYZ as out of stock. If I change XYZ to 1, well, now I have two items in stock when it really is just one.
Within Search & Discovery when I go to create a filter, the options are the variants that I create which ends up being a problem if you try to have two for the same product, or other values that don't quite fit. Maybe if I could add custom category metafields to "Non-Sports Trading Cards" but I don't see an option to add a custom field to it.
What's the best way to go about doing this?
