[Harlowe] How to make a variable name itself?

Let's say I want to create some random characters. One way to do this, in my twisted imagination, is making a $namecreate variable that creates one name, then I would make it dump that name in another variable specific for that character (let's say it created a bartender, and dumped his name to a variable with the name of the character)

Is there a way for a story to generate, or at least rename, variables along the way?

Or is there another way to create this effect for the player?
