you might be able to set a variable to the most recent trigdate() and
then do some math on it to create the other event.  Something like

  OMIT Nov 26 2020 # Thanksgiving
  REM Thu SKIP SATISFY [$Td < 3 || $Td > 9] MSG Thursday thing
  IF trigvalid()
    SET meeting $T
    REM [meeting-6] RUN send_email -s "Send mail for [meeting]"
  ENDIF

Based on a quick check, it seems to do what you intend.
