[Remind-Fans] reverse OMITFUNC?

[Matthias Teege]

Hi,

I'm using OMITFUNC to remove reccuring meetings from my calendar
during vacation like this:

 FSET vac(x) isomitted (x) || \
   (evaltrig("2019-01-01 *1 UNTIL 2019-01-04", x) == x) || \
   (evaltrig("2019-02-01 *1 UNTIL 2019-02-04", x) == x)

 REM Wed SKIP OMITFUNC vac MSG Meeting%

How do I add a new entry ("vacation") to my calendar using the dates
from the function? I would like to avoid writing the dates again.

Thanks!
Matthias
