Unreal Engine 4 Progress Bar Material

I am looking for someone who has a great experience with UI Materials. Looking to design a material with the same functionality as the one in the screenshot below. which has health and shield, when the player has a shield it takes over x% of health depending and when there is no shield, the health takes over the whole area. If you can do it, please let me know, I will provide with the material of health which is already complete. Only requirement is to add the shield functionality.
