title: Custom row labels in PivotTable
body: <p>I have an excel spreadsheet full of customer data including a few single letter categorical variables.</p>
  
  <p>For example: property type can be (I for investment, O for owner occupier, or R for renter).  Is it possible to replace the single letter with a descriptive title in the rows on a PivotTable?  I do not have the descriptive names anywhere in my spreadsheet and I would prefer not to add them.</p>
