Boundary conditions on internal boundaries

I have a problem applying boundary conditions to internal boundaries.
My model is a simple block and I drew a smaller rectangle on one of the faces (i.e. an internal boundary, see file attached).
With this configuration I am able to apply the the "Boundary heat source" and the "Highly conductive layer" conditions to this interior boundary, so no problem.
Problems start when I add an additional entity to the model and form an Assembly (not an union). I am then not anymore able to set these boundary conditions ("not applicable") and I don't understand why.
I suspect it has something to do with the assembly, but I am struggling with this for a while.
Any suggestions?
Many thanks,
Julien

can you explain what woiuld be the necessity to use assembly in the situation of this model?
Assembly does not create any internal boundaries, all objects are siolated unless they are mated
using the pair conditions.
If this explanation does not help, send the mph file so we can help.
