Instance, array and mirroring


I’m trying to figure out how to modify instances in a circle with a mirror

point in the center. I came as far as making an array but I only managed to mirror them from a center figure (see attached image, figure A). Instead, I’d like to have the mirror itself in the center point so I can adjust from a figure in the circle itself (figure B). I have looked through several tutorials but I haven’t found anything that covered this specific kind of instance mirroring so I’m not even sure if Silo3D is able to?
