Force Pivot Table Rows/Columns to Show When No Data Present

I considered creating fake records that have null values for either Likelihood or Consequence, then force-hiding those N/A rows/columns from the pivot table. I had mild success with this method for preserving the 5x5 matrix, but it is messy and not a robust long-term solution. Was hoping someone with more JS experience than me might think of a straightforward, if not simple, solution.
