The new save system can now load saves without reopening the level, this can be done by calling the Load Save event in BP_InventorySaveSystem.

Here is an example of the new Load Save function, the Save Name is the save that will be loaded when the event is called.

In Game Reload must be set to true if you are loading a save while playing in game as it clears the level of actors not included in the save that is being loaded and resets the player characters.
