To anyone with NOTIS LSER experience:

How do you code patterns for titles which publish monthly "except for two
issues in April and Dec."  We have tried everything we can think of and
nothing seems to work.  The title in question is:
Fett Wissenschaft Technologie = Fat science technology

It is published once a month except that two issues are published in April
and December.

How does one create a workable pattern for something like this, or is this
one of those titles for which no method will work so that the prediction
will work as it should?

Any help would be appreciated.
Thank you.
