Set up save/ load system

Hello everyone, i am fairly new to programming and UE4, so i have a noob question concern save/ load system. I have a bunch of different blueprints, each of them got around 4 and 5 values need to be stored into a save game, so what should i do? Set up a big save game class that in charge of storing every values of every blueprint instance or make a bunch of small save game class that each of them is in charge of a separate blueprint?
Thank you very much for reading this far.
