How do I use Sprites materials in flipbook instead of Flipbooks material

I’m trying to implement normal maps to 2D sprites. I was able to add the materials to the sprite itself, but the Flipbook ignores it and uses its own material, rendering the applied normal maps useless. Is there a way to disable the flipbook material or make the sprites use it’s own materials in the flipbook?
