Some components need multiple catalog entries. Define them in the Circuit Builder spreadsheet to add them in the Setup & Annotation section of the Circuit Configuration dialog box.
Notice the values in TABLE0: PB and TITLE0: Push Button.
It indicates that the component can have a main catalog value. The TABLE0 value is the table name for the catalog lookup. The TITLE0 value is the title for the section in the Setup & Annotation area of the Circuit Configuration dialog box.
The next time Circuit Builder is run using the configure option, an extra catalog section appears for this component.
