MODO Texture Animation

Hey, I've been using MODO for 3 months and have a background in Maya and Blender. I'm still trying to adapt and learn this software so there's plenty of functions that I'm unknown about.
I modeled a robot character in which I would like to:
- Animate 2D expressions, from "Happy" expression to "Sad";
- Move the 2D face freely on the mesh it's textured on.

Haven't managed to find much useful information about it online, the closest I got to it was finding a way of creating a mesh and animating expressions through it and animate through the GraphEditor, however this last one didn't seem to do anything.
Any help?

Thanks in advance
