[Remind-Fans] OMITing one date from a range

[remind at isaacgood.com]

Hi all. I'm trying to set up a weekly meeting from date A through B missing one date. The OMIT part isn't working for me.

Working reminder:
REM Tue 13:30 *7 UNTIL Jul 11 2012 FROM Mar 27 2012 DURATION 0:30 MSG My Meeting

Apr 3 I got a conflict and am not meeting then. So I tried:
REM Tue OMIT Apr 3 2012 AT 13:30 *7 UNTIL Jul 11 2012 FROM Mar 27 2012 DURATION 0:30 MSG My Meeting

That line seems to schedule it for *just* Apr 3. How can I skip Apr 3?

Thanks!
