This Question is not specific enough to say for sure, but if you were to Select the GameObjects to Load in GameObject Variable Slots from the Respective Variables in the Inspector, you can make all Items into Prefabs (of Course they need a dedicated Folder for Items), and put the Prefabs in the Inspector Slots.

I’m Beginner at Unity, so I’m not sure if it’s even possible to be correct what I say,
but I hope it helps.
You should better think about if my Answer could be right or is doomed to be wrong before proceeding.
