[Orgmode] logbook + (re)schedule

[Fredrik]

I use the schedule and logbook parts to keep track of contacts and  
remind me when I haven't had contact with someone for a while like  
this...

* CONTACT Someone Somewhere
  SCHEDULED: <2010-01-28 Thu .+21d>
  :LOGBOOK:
  - State "CONTACTED"  from "CONTACT"    [2010-01-06 Wed 19:58] \\
    Called and said hi
  :END:

This works like a charm... but is there someway I can add an entry to  
the logbook and have the schedule rescheduled for a specific date? Say  
I actually talked to the person this weekend but didn't get to a  
computer until today can I then add a entry for Saturday?

CONTACT/CONTACTED is just my words for TODO and DONE...

Regards,

Fredrik
