Notes:

• As of July 2019, this is lower priority but builds on previous work from the overdue loans report.
• Bold-face fields above represent the ones that are not currently included in CSV export.
• Some of the existing fields in the loan export have been reordered in this story to make it more consistent with the overdue loans report.
