Not that I know of, since playing techniques use the Font Styles and not the Paragraph Styles. Maybe Shift-X text is better, and use a hidden Playing Technique if you need playback.
I managed with Finale Jazz text font since it has these extras.
Or you can create them in Affinity Designer/Adobe Illustrator or similar and export them as SVG:s. Then import then under Type: Glyph in the Playing Technique editor.
