When filling out columns like, say, the observation.observation_type_concept_id or the visit_occurrence.visit_type columns it would be nice to see the list of possible concepts (and their concept_ids) associated with those columns. The list of possibilities is small and the query to find the associated concepts is straightforward. Many times while we were working on the SynPUF ETL, @ericaVoss had to hop out of Rabbit in a Hat to look up these possible values and it seems like we could avoid this.
