Adding Anisotropy Channels or Inputs to Material Blend Node?

I have two materials in their own graphs I want to blend together with the Material Blend node, and cut some areas out with a mask.
However one of the materials I've made has Anisotropy and there isn't an input for Anisotropy Level or Anisotropy Angle in the Material Blend node. Is there a way to create an input or chanel for these maps?
