Can I use GUIStyle and make the button's textures MovieTextures instead of regular 2D Textures?

I want my buttons to be looping .mov files because I want their text to be moving with animation I used from After Effects. So ideally, I want my button's normal state to be a MovieTexture, hover state to be a MovieTexture, and active state to be a MovieTexture.

Using GUIStyle, the only option is to select normal textures for button states, not movie textures. Is there a way to use movie textures for button state in the GUIStyle variable?

Thank you Jon
