Extend Repeating Meeting?

Is there a way (for a meeting owner) to extend a repeating meeting (add dates)? When you open a previously scheduled repeating meeting, you can view the dates, but cannot edit them. You can reschedule the time for one instance (or all past/future instances). However, I see no way of extending a repeating meeting. Am I missing something, or do you have to create a new repeating meeting for the dates you want to add?

Subject: Cannot extend

This is not a function in Lotus Notes - you must create a new entry. Using the Copy Into New Meeting function will copy over all of the relevant information (attendees and rooms, etc)
