Varying items for single recipe slot. 1.18.2

Heyo I've tried some stabs at trying to make a recipe that uses a group of items for a single cell in a recipe, say slot y in the pattern can have multiple varying items for its recipe how is it suppposed to be written? { "type": "minecraft:crafting_shaped", "pattern": [ "yw ", "xz ", " " ], "key": { "y": { "item": "itemy" }, "w": { "item": "itemw" }, "x": { "item": "itemx" }, "z": { "item": "itemz" } }, "result": { "item": "output", "count": x } } Is it written as: "key": { "y": { "item": ["itemy", "itemy2", "itemy3", "itemy4"] Or do you repeat the recipe format for each item multiple times like: "key": { "y": { "item": "itemy" }, "key": { "y": { "item": "itemy2" or repeating the entire recipe multiple times with a different variation for y? If none at all what steps would be needed to make a group of different items for slot y?
