Custom Export Field Names in Ad Hoc Analysis

Hi All !  Glad to have learned about this forum at the Adobe Summit ! (Thanks SMacDonald2008!)

I'd love to know if it is possible to change field names for data exports that include segments in Ad Hoc? For example when I copy or export a report, it lists the segment names as well as the date:

Is it possible to have the field populate as a standard date?  (2/2/2014)

If not in Ad Hoc, can I do this in Report Builder?

Thanks!
