.txt to GUI Label

I want to create an object that opens a messagebox when the player walks into it’s trigger. Is it possible to create a script that accepts .txt files via the Inspector and displays its content on a GUILabel? Or would I have to write a script that parses external .txt files?

(I know I could use a String variable, but then I’d have to write each message into the inspector. It would work, but I want to have it easier/more elegant)

Scratch that…found the type I need: TextAsset.
