getting a player's name

I want to make a dialogue based game, sort of like Episode but simpler, and my story's fine except for one problem. I don't know how to get the player's name. Is there some way to get input in the Inkle editor? Like I want to set a variable whose value is equal to the player name, then be able to use that variable in a sentence. Can someone please let me know how to do this? Oh, and I'm using Unity in addition to Inkle, but separately.
