Re-using basic shapes in an icon font

I’m working on an icon font, which has always an outline circle around different icons itself. Is there a way to define this circle one time and re-use it in all the other glyphs? So if I want to make changes I can do them on this particular “master circle”. Thanks

You can use components for parts that needed multiples times. Create a glyph called and reuse that glyph as a component in other glyphs. For more, see

That works great, thank you
