Is there a workaround for using 2D sprites as UI Elements in UMG?

I currently have a large number of 2D game sprites that are meant to be used as UI elements (think “Heart Sprites” from traditional games like LoZ, or “Lives” in Donkey Kong or Traditional Arcade Flyer games). The problem is UMG images currently only support textures.

Research has basically shown me that currently UE4 UMG only supports textures/ materials. So my question is simply:
What is currently the best workaround that peeps know of for getting UI sprites (all contained in the same spritesheet texture) into UMG?
