I'm following this tutorial:

I have a Sprite node with an AnimationPlayer child node. I have a single sprite sheet that has one full animation and a bunch of single-frame placeholders:

Until I create the rest of the animations, I'd like to switch between these placeholder animations.
My question is: is there a more efficient way to show a still frame using the animation system? Currently it seems like my single-frame placeholder animations play for one second. Is there a way to just make it a "still" frame? Is there a better way of doing this (without creating a Sprite node for each animation)?
