Is it possible to have two physical materials in one material?

I created an asphalt material using the puddle function from a Megascans blend material. I want to add sound effects and visual effects when the character steps into the puddle. The puddle function doesn’t support applying physical materials. It seems that the Megascans blend material doesn’t include any information about the physical material for puddles.
