Save Point System Tutorial

Hello again forums!

I’m looking to upgrade my perfunctory save system with something a little more meaty. Right now I can press F6 to save and press F7 to load game. But I want to replace this “quick save” system with a “save point” system, kind of like Resident Evil 4 (the typewriters) or Silent Hill (The Notepads).

Is there a tutorial out there that will show me how to make a save system where I can walk up to an item, press the use key, it brings up a Save/Load screen and I can save in a slot or load a slot?

Any information is appreciated, I’ve checked YouTube, these forums, and done internet searches plugging in various keywords but I’m not quite finding what I want. I may have to puzzle it out on my own, but a tutorial would be way cooler!
