What are you looking to do with the additional columns? If you have multiple fields of text that you want as input to the graph extraction, you can concatenate them in a pre-processing script. But we don't currently support any form of metadata/column-based filtering, so I'm not sure what the use case is.

Curious what the point of supporting CSV is if you cant select which columns to use?
