How to add radiation heat transfer to 3-Zone Pipe (2P) ?

Hi, I would like to know if there is a way to add radiative heat transfer to the 3 zone pipe? Problem is, thermal port outputs after convective heat transfer. Radiative transfer needs to be parallel to the convective transfer. I am trying to model a simple condenser with significant radiative heat transfer.

I wonder whether it can work if I input equivalent resistance (convective and radiative) to the External environment heat transfer coefficient?

This may be a workaround:

May the convective transfer coefficient in the 3-zone pipe ridiculously large, so it results in almost no thermal resistance. Then you can add parallel convective and radiative heat transfer to the H port to do what you want.
