How to pass data from my Administrator menu to my playable level?

My project requires the creation of an administrator mode, where the administrator sets the difficulty and the other properties of the playable level (a ship simulator). He creates a game, he sets the number of fires, their intensity, etc etc… The setting of properties is set by the use an Administrator’s Menu with many options. How can i pass these option (variables?) to my playable level?
Are there any tutorials or documentation? I tried the Save/Load game tutorials but they are not what i need.
Thanks in advance!

Is there a way to develop this using only Blueprints? Is the use of C++ neccessary?
