If you populate the building_name and room_name columns with the Building Name and Room Name in the data import file, the software automatically associates the corresponding Room Number with the course section and populates it on the course section. 

Given that, the Room Names need to be unique under each Building in Core > School > Buildings which is not how our Building naming convention works. 

It would be easier for us if  you include the room_number in the file layout help so we can just import this if we want to.
