How to animate UMG sideways?

Ok so I have this image and I need it to expand from one side (left) to some spot on the x-axis. But when I animate it using the transform (scale) function, it expands from the middle of the image outward on the x-axis. How would I animate the image to expand from the left instead of the middle?

The image I want to animate are the images with words on them, so when you hover over the button, the image opens outwards to the right.
