I have a request I want to schedule to run every Friday.  However there are certain weeks where the Friday won't work, and it has to be moved to a Thursday.  So I'd like to set a scheduled request to run every Friday until the week before it needs to run on Thursday.  Then schedule a once-off for the following Thursday and then a recurring event for the Fridays after that.

Because I can't do it this way - I'm stuck scheduling one-off events for every date I want it to run.  I end up with multiple one-off events rather than just a couple scheduled events with start/stop dates.
