Changing sprite animation based on top-down pathfinding movement

I'm working on a top-down game with moving NPC sprites, and I'd like to use different animations based on their direction of movement. They all have 8-direction behaviour, but the only way I can see to change animations based on direction, is with keyboard input. However, these aren't player characters.

I've found the "8-Direction -> Is Moving" condition, but no conditions or actions relating to direction of travel.

I've tried doing it by object angle, but the object doesn't have rotation enabled. I also tried adding an invisible pinned sprite and rotating that, but I still can't find any conditions that would enable rotation based on direction of travel

Ok, so I found the Moving Angle and CurrentNode expression for the Pathfinding behaviour, and have changed the sprite to rotate towards the CurrentNode it's walking towards.

However, I tried to change the animation based on angle, but I don't understand how the angles are decided. Is it relative to the node (with straight forward being 0 degrees), or is there a 'global angle' based on the layout that I can use?

This is what I have now, and the animations are all over the place during Preview
