Along with Spark or Smartexchange or whatever importer you use, learn to use Excel and Total's worksheets along with the csv files for your data sets, and maybe some of your own databases for neighborhoods, and zoning references, and census tract data ... you can pass the grid back and forth between the two programs, reference information from the datasets, and develop whatever semi-customized template of any length you can imagine, that can be pasted into your supplemental addendum with a copy and paste of one cell. Build your template a paragraph/section at a time, and build your databases neighborhood by neighborhood, municipality by municipality, zoning reference by zoning reference, as you do the work. Anytime you notice yourself repeating a process that could be automated, figure out how to add this to your customized spreadsheet. The worksheets have limits, but can also empower you to produce cohesive reports that are detailed and consistent, and allow you to focus on unique commentary relevant to the appraisal problem.
