The only option available at the moment is to use the Batch Import feature, place your files in folders named after the metadata, and enable the option on the batch import screen to populate metadata from directories. Then you can have as many fields filled in as you want, but it will probably take a little bit of time to put all of the files in the folders before batch importing.

I do have plans to address this, including supporting an option to import multiple pdfs through one csv, and an option to import a CSV just to update metadata for existing songs in the library.
