Extra/Existing fields in OneSpan Sign

We have been using the "name" field in Packages along with "description" field.  Is there another field that we could dedicate for our use? 

For example, and Ideally, we would have a "drop down" box with pre-determined values so we can capture Business related process info, for example a certain type of Loans or Mortgages. This way we can extract/report with certainty that is not available from free format text fields.
