interCondensatingEvaporatingFoam and Heat flux

How to provide constant heat flux boundary condition with interCondensatingEvaporatingFoam ?

I have this long standing question and haven't got an answer yet. I am wondering if someone has solved it.

You can use the type externalWallHeatFluxTemperature for the wall, so you can have a fixed heat flux (for example 20000 [kW/m2]).

in 2023 I still have this problem. the externalWallHeatFluxTemperature BC is unavailable for interCondensatingEvaporatingFoam.

Is there a way to add this BC manually to interCondensatingEvaporatingFoam, such as adding some libraries to original solver, make files etc. ?
