Forced Convection in COMSOL 4.2

I am currently using the new built-in feature of COMSOL which is the forced convection. It really makes life a lot easier since I do not have to calculate the heattransfer coefficent myself, COMSOl will do this. However, the only three options of convective cooling are: Air, Water or Oil. In my case I want to recreate my experiments and then I need a mixture of Argon, Ethylene and Hydrogen.

I can not find a way to do this in COMSOL. I already tried to change the properties of built-in Air (changing the specific heat formula, thermal conductivity and dynamic viscosity to the right one for my mixture) but that doesn't seem to help. Does anyone know how I can solve this problem?

Thanks!
