You can create them in the chords libraries, in the form of new chords, using the Options menu , Chords library item. Only Pizzicato Professional can add chords to the original library. Notice that in this case, the chord notation will also include the name of the note, for example "C 6".

You can add this figure under the staff by using text blocks.

You can add it by using the lyrics tool, exactly as placing syllables under the notes.

You can create a new tool palette (Pizzicato Professional only) and add to it the symbols of the main figured basses.

For solution (4), here is how to create a simple text symbol in a palette.

Create a new palette or use an existing palette. To create a new palette, select the New palette... item in the Tools menu.

Open the graphic symbol palette. It contains a "coda" simple text tool. While holding down the CTRL key, drag this "coda" symbol into the palette where you want to add a text symbol and release it. A dialog lets you select "Duplicate". Validate. A new "coda" symbol appears.

Double-click this new "coda" tool. Modify its name in the upper part of the dialog and then click the "Create/modify…" button.

A graphic editor appears. Double-click on the "coda" small text displayed in the upper left part of the dialog. Modify the contents of the text in the dialog box and validate. Close the graphic window and the dialog of the symbol. The text symbol is ready. When you want to use it, select it and click in the score.
