Count Unique using Pivot Table
 

I have underlying data that looks like this:

Region Cust # Creat Yr Sl Year Month Sales
MW 100 2007 2007 5 $500
MW 100 2007 2007 12 $700
MW 101 2005 2005 1 $100

What I want to get to in my pivot is a count of new customers by region:

Region Create Yr Sales Yr
2005 2007
MW 2005 1 0
MW 2007 0 1

I saw the posts referencing http://www.contextures.com/xlPivot07.html#Unique
however, the underlying data is coming from a non-Excel source.

Is there anyway to obtain these results in a pivot without creating an
additional column in the underlying data.

Thank you,
Beth
