Use WorldAlignedBlend AbsoluteWorldPosition and LandscapeLayerBlend together

I have watched a number of tutorials on each and can alter landscapes based on them. I have a landscape using LandscapeLayerBlends that allow me to paint and auto material the terrain, add foliage, etc.
I have another that applies the materials based on WorldAlignBlend so you get texture on slopes.
My issue is I can not find any information or tutorials that show mixing these so I can paint (if I want to) use vegetation/foliage on the layerblends and have slopes with different materials and certains heights (beach, mountaintops) have their own texture.
Anyone have a good tutorial on this or some tips?
