sorry for the misunderstanding @jreback. The following sample code compare output between using multiindex vs singleindex column only. ``` python df = pd.DataFrame(data={"X":["test1","test2","test3","test4","test5","test5", "test2", "test3"],"Y":[0,1,2,2,1,2,10,3], "Z": [1000,300,400,500,2350,100,100,1000], "A":["category1","category2","category2","category3","category4","category4","category5","category1"]}) # pivot...

@chris-b1 : Correct, the concern is more to the feature consistency. I assume if new format will be applied to both single column and multi index column. Thanks for clarifying...
