I added the 2024 HW Motor Show 5-pack, without the dollar general sticker since it is in there twice, and the Mopar 5-pack 2024 to owned tonight and I thought it would also flag the cars automatically contained in the set as owned. It didn't when I checked. Currently it looks like you have to add each car and the 5 pack to the correct status unless I missed something. I usually look up 5 packs first since it is quicker when I am in the store checking for a possible duplicate.

I am guessing since currently the 5 pack doesn't directly link to the cars in any way this might be why. The cars do link to the 5 pack though if you look up each car though so I don't know if there is a way to link both ways like maybe a fourth field below Year with Cars that links to Series Mopar 5-pack page just like if you tap on the series page under the car now.
