Pivot cache
 

I found in "http://www.contextures.com/xlPivot11.html#Top" a program that can
use the same pivot cache for all the reports within the workbook. Two
questions: will using this program reduce the size of the overall workbook?
And is there is way to help me modify this program so that I can cache a few
reports to be used in a workbook (as opposed to one)? Many thanks (in
advance)!!
