[horde] Delete past recurrent events

[Louis-Philippe Allard]

How do you delete recurrent events that are past?  Lets say I create a new
recurrent event every Sunday morning.  Once the event happened, I want to
be able to delete it and have only the future events in my calendar, no
past events.

   I understand hoe to create a new recurrent event, but there is no delete
button that allow deleting either current, future or all (current &
future).

   Thanks!
