Aggregate values without using the pivot table or subtotal
 

Hi All:

I'm looking for an Excel addin that will aggregate values without
using the pivot table or subtotal menu commands. I need multiple
functions as part of aggregration like sum, median, average, count,
unique values, etc. I've seen a commercial program called DigDB that
has what I'm looking for but I'd prefer something free or open source
(wouldn't we all). Any thoughts?
