Is there a way to change the texture file in a texture sample in a material from blueprints?

This would help my intended simulation greatly if There was a way. Mostly I’m having a hard time finding the proper node/reference. Can anyone clue me in?

Check out this video.

I’m talking about changing that rock texture sample node to instead be a brick texture (TGA) and change during gameplay when triggered to.
