Does Org Mode have a way to identify that multiple events refer to the
same event?  It would be wonderful, for those of us with messy org files
(multiple overlapping incoming data sources), if Org Mode had a way to
to relate multiple events in a way that sums the details between events.

For example, assuming I had two org files, customer.org and calendar.org
(calendar.org being some form of exported ical-file):

  ~/customer.org:

    * TODO Meeting with Pete
      :PROPERTIES:
      :See: [[file:calendar.org:*Meet%20Pete][Meet Pete]]
      :END:

  ~/calendar.org:

    * Meet Pete
      SCHEDULED: <2013-04-19 Fri 09:30-10:00>

When exported into an agenda, the consolidated org agenda would read:

    Friday   19 April 2013
      customer:  09:00-09:30 Scheduled:  TODO Meeting with Pete

Are these wild dreams just dreams, or does Org Mode support such lovely
magic?
