Thanks very much Keith. Ok I checked, and I was in master view in my setup. I do have a whole house model setup there ("all") and I see it in the listing of models to which I can drag & drop models from the donor sequence. I set the donor sequence into master view then rendered/saved it in case that might make a difference. I also made a new "WHM" group with all elements, rendered, saved the donor sequence, to see if that would help. Not seeing either of the whole house models in the drop down. All the other models seem to be available in the drop down.
