Method for creating actor with random animation?

Hey, I would like to know how I can create an actor with a animation randomly picked? Is there any way to do this without switching animations right after creation?

The toolset doesn't allow you to pick a random animation form the start, so you're stuck with the solution you don't want to use.

Is there any reason to not switch animations right after creation?

I think that you want a random animation, but it's possible only by an event. I attach an event image and you build it in your game.
You must remember that the name "green", "blue" and "red" (or you put) are the names of the character animations.
