Save Game system for consoles (ps4 and xBoxOne)

Hello,
I’m developing a game that will be released at least for PC and PS4.
I’m developing a quests save system based on the USaveGame, I created a basic save game class and the designer creates one blueprint based on that SaveGame class adding the vars that he needs for every quest.

The problem is that the engine creates one archive for every quest saved and I dont know if this is the most accurate way to save the quests states.

Is this way to save possible on ps4?
Am I going to have one save archive for every save also on ps4?
Is this allowed by Sony’s TRCs?

Thanks
