Fast SSS and bump

I’m trying to figure how can i make a skin shader with the vray fastSSS and a bump map.

The problem is there isn’t bumpmap slot in the vray FastSSS shader.

I know the right workaround is putting the fastsss map on top of a vrayblend map.
But, where i should put de bumpmap?

Normally you would put a specular (or specular+diffuse) material as a coat material; this is where the bump map should go.

How can i do the color of the coat material doesn’t affect the colors of the base mat?

Use a VRayBlendMtl material in Additive mode.
