title: Custom Column Filter on Pivot Table in Excel
body: <p>I have an Pivot table in an Excel Sheet where i want to put an custom filter on the label Worktype.
  The Worktype can have only 5 values i.e. 
  Non Production, REX, QA, RES, BP.
  The filter should be like this that:
  IF(WorkType Contain only "Non Production) then Show "Non Production" in WorkType, 
  else Hide "Non Production" in WorkType and show remaining WorkType (REX,QA,RES,BP)  .</p>
