Hanged radiant panels in the zone

Hello there!

I am struggling with a problem of a tall attic space, where it doesn’t make sense to cool the whole space to a certain temperature. Therefore I would like to use hanged radiant panels, which would be at certain height of the room. Is there a way to model this using existing ladybug.tools components? It is my understanding, that it might be doable in the OpenStudio using components:
Construction:InternalSource

ZoneHVAC:HighTemperatureRadiant

ZoneHVAC:LowTemperatureRadiant:*

as it has been pointed out here: https://unmethours.com/question/3130/how-to-model-roof-hanging-hot-water-radiant-panels/,

or am I wrong? Also, would I need to separate the room into more airnodes?
