Name a constant?

I’m trying to set up a material that will let the artist select from a preset list of metal presets (gold, copper, iron, and so on) by choosing from a list. Is it possible to do such a thing without using a blueprint? I played around with a simple set up that took a number and selected the proper pre-set, but I’d rather the artist see the metal by name rather than have to remember that 1=gold, or something like that.
