What's in the Box?

Would love to have a "What's in the Box" Feature. I got a Welcome Pack 2026 at Spiel that had a Promo Card inside. But i have no way of knowing what i can pull from these.

Because the 6 Cards that could be in that pack are inside a "Promo Section" with thousands of entries. I'm not saying make a "Set" for every little thing ofc. that would be Overkill, but instead a function that tells me what Cards are inside a sealed product. If this will be a Button or something else is up for debate. Having it shown under the listings would be cool, but only feasible for small packs and not entire Sets. So basically a bridge between Sealed and Singles, so that they actually relate to each other and are not standalone entries.
