I believe "OMIT -1" is not legal syntax.  Here's a solution, not sure if
it's optimal or not:

   REM Sat SATISFY day(trigdate()) > 7
   REM [trigger(trigdate())] -1 MSG something happens

The strategy there is to first find Saturdays that satisfy your
condition, then place the reminders as a second step.

I don't believe it's possible to get advance warning on a calendar
output.  (Personally, I think that would be a rather weird feature.)
You will get advance warnings if you generate a reminder list repeatedly,
for some series of days:

   rem -q Apr 6 2006 *10

I think most people handle task lists by generating reminders that run
every day after some trigger, and simply deleting them when done.

   REM 12 Apr *1 MSG file taxes
