[Orgmode] How to "snooze" a repeating item

[Andrew M. Nuxoll]

I've been using org-mode for four months now and I just love it.  So I 
think I'm post-newb but still very amateur.

Anyway, my to-do list has several repeating scheduled items like this 
contrived example:

***** TODO [#B] Lunch date with Sarah at 12pm
     SCHEDULED: <2009-12-08 Tue +1w>

Or, in English, I meet with Sarah for lunch once a week on Tuesdays.

Now, let's say that Sarah calls on Monday afternoon and says, "Can we do 
lunch on Wednesday this week?" and I say "Sure thing."

Now I have a problem.  I could shift the date to Wednesday like this:

***** TODO [#B] Lunch date with Sarah at 12pm
     SCHEDULED: <2009-12-09 Wed +1w>

But that will mean that the following week it will *still* be scheduled 
for Wednesdays (specifically Dec 16 instead of Dec 15).  I miss my 
regular lunch date with Sarah and catch ire for standing her up.

How do I handle situations like this? 

It seems like I either need a time stamp "stack" or I need a temporary 
flag that "self destructs" after a prescribed time.
