How to define angular dependent reflectivity in Surface-to-Surface radiation?

Hello,
I am working on a simple 2d radiation problem. I have defined an angular dependent surface emissivity function. When the emissivity is reduced, the reflectivity must increase for an opaque body! With varying incident angle the surface emissivity is calculated correctly, but the reflectivity is not updated by (1-emissivity(theta)). How do i set this up correctly? There is no document for that. I can only input a constant "diffuse reflectivity" not a angle-dependent.
My current settings look like this:
Thank you!
