You can define what program genres are to be included or excluded from a daypart definition. Select a type by clicking on it, and select multiple types by control-clicking on additional entries. You can sort the entries in the list by clicking on the column headings.

 

 

Click on one of the radio buttons on the left to note whether programs with the chosen types should be included or excluded from the daypart.  For example, you might create a daypart line for sports events.  Or, you could define "prime" to have all programming except sports events.
