Non-Premixed Combustion Methane

HI is someone familiar with non premixed models in Fluent? I'm using Pdf equilibrium and steady laminar flamelet models, but i'm not able to change the transport properties for the pdf-mixture, it only gives me the possibility to set it as a constant or as a polynomial, but i'd like to set it as mass weighted mixing law

Mass-weighted or volume-weighted mixing law implies properties being dependent on the species fractions. This is not permitted in the non-premixed model for transport properties.
