Only Surfaces are allowed in Steady-State Thermal if Imported Loads (MAPDL Results File)

I have a Steady-State Thermal system and want to import load via MAPDL results file ".rth". I can only scope the Imported Load (Temperature) to surfaces, not bodies. However, in Static Structural system, I am able to scope the same imported load to bodies. Not sure why the same imported load is treated differently between these two systems. I have a user who requested to import load to bodies in Stead-State Thermal system. Before filing an enhancement request, I post the question here and hope to get some input. Thanks.

    Hi Chris, for a thermal analysis, if you assign an imported temperature field to a body, then there's nothing to solve for within that body (all the temperature DoFs have already been prescribed), so essentially that body can be replaced by its boundary surfaces where it connects to neighboring bodies, hence why I think only surface selections are allowed.
