How do I get a reminder on a certain date for a future deadline without Sandy trying to logically link together those dates?

I frequently have a deadline or appointment coming up that I need to ensure I don't forget with a tickler. So for instance, say that I want to make sure I renew my Drivers license by 6/13. But I am only out of the office Tuesday morning, and no other time until then, therefore I try telling Sandy:

remind tues 9am Renew Drivers license by 6/13

Instead of telling me "Renew Drivers License by 6/13" on Tues 9AM, she strings together these two apparent dates illogically:

Fri, 6/13 9:00am - Wed, 6/3/2009 9:00am Renew Drivers

This doesn't make sense! I want Sandy to remind me on Tues, then I can snooze it for 24 hours or so if I can't go get my driver's license renewed.

How do I make Sandy understand me??

Thanks!
