Ok. I was thinking of just extending an existing schedule with a simple
click for a "run additonally" exception, but this is maybe too much
effort for very rare cases.

Ok. I'm usually not designing data models using vector/array datatypes
because inter-db portability issues are always implicitely considered by
some cells deep in my brain.
In case of exceptions, IMHO it's a bit unfortunate to use them, because
adding/deleting a single value would always mean to modify the whole
column, so I'd still prefer an additional table (jexdorun omitted).
