Save external blueprints

Hi, When i create blueprints whether it’s for constructing procedural fences or a lamp i can turn on/off etc to use in my game. Is there a way to save them as an external files so that i can use them in another UE4 projects. I would like to set up folder with subfolders that’s independent from UE4 on my PC were all my created blueprints are stored so i can add whatever i want to my various projects. Is this at all possible?
