I have a "Buildings" content type. Within that content type I have a building_id field, which contains the building ID.
I have an "Employee" content type. Within that content type I have an entity reference to the Buildings content type.
I have a CSV file for employees but it does not have the building label or the node id, only the building_id.
So my issue is that when I run the employee feed import, I cannot add the building since I only have the building_id.
How would I map the building_id in my csv to match the building_id in the building content type so that it knows which building node it is referencing?
I hope that makes sense :)
