Is it possible to customize the list of functions available under the Field
Settings command in Pivot Tables. The list of functions only includes about
a dozen basic functions (e.g.; SUM, MAX, MIN, AVERGE, etc.). I have tried
customizing a calcualtion but that only allows me to create formulas; it does
not give access to the "paste function" and its underlying list of functions.

Thx,
