Natural harmonics circle size

I would like to alter the size of the circle of the natural harmonics in Dorico but can’t seem to find an option for it anywhere. Am I not finding the right place to adjust it or is it currently not possible to alter the size of that circle?

Cheers,

It’s under Library > Playing Techniques… > Common > Harmonic (o) where you can click the pencil icon to scale it up/down. This also alters the glyph on harmonics that you set in the Properties panel.

Thanks, I thought I looked there but obviously I missed that one.
