[UMG] Background image or color for UMG vertical box

Well, this is how I originally approached it. My setup consists of a vertical box that contains 3 text blocks (title, subtitle, and info) and a horizontal box (3 buttons). My info text block is in a sizebox to allow for my buttons to rise/lower with the height of that text block. So my problem is anything outside of the vertical box is static and unresponsive to my dynamic changes, and if inside the vertical box, it just gets put into the hierarchy of the contents.
