A variation of this which was worked out a while back was using characters from a font for the dividers in a round box (because it was kind of trying programming some of the variations, or because it’s tedious re-generating and re-assigning toolpaths, take your pick).
Here’s the font:

It works when placed in the Carbide 3D font directory (Help | About | Open Data Directory) — I doubt anyone would want to install it.
Here’s the file:

Just load the font, select the center divider, then choose the font tool and replace the number with the number of dividers you want.
