Default UDF for species mass fractions

I am working on a species transport problem with two species mass fractions involved. I would like to write an UDF for the mass generation of the two fractions A and B. However the mass generation of either fraction is dependent on the concentration of both the species i.e mass generation of A or B is a function of both [A] and [B]. Is it possible to write an UDF of this kind for FLUENT.
