Defining transient external Black Body Temperature Method

Hello guys and girls,
I am currently performing a transient simulation of a room subjected to the outdoor weather conditions (air surrounding the room is modeled too). When setting up the boundary conditions for my inlet surface, under the radiation tab there is an option to define the "External Black Body Temperature method" which in simple words is the temperature of the sky vault which will be used for the radiation exchange between the wall and the sky (S2S radiation model used). Fluent allows you to define a different temperature than the boundary condition temperature however it doesn't allow you hook a UDF and change that temperature with time.
Does anybody have any clue on how I can define a transient black body temperature or in different words, how to define a transient parameter when fluent doesn't give me the option to hook a UDF?
