Can we do Blend Materials?

Is there a way to do blend materials or some sort of workaround in PlayCanvas?

Use case,
I have a wall of bricks. The default texture is tiling bricks. I want to add a extra layer of texture for smudges and crack on top of it.

I want to be able to change that second layer at any point during runtime hence why I don’t just do the texture in photoshop.

Not my area, but I know something like this as been done and will need it’s own shader AFAIK.
