If you have created a left nav component on the homepage artboard for instance, and you want a link in that component to always come back to the homepage artboard, then there's no way to set it up. Other than to make individual instances on the other artboards whereby they link to the homepage artboard. Maybe the overlay someone mentioned would work but that seems kludgy and like a workaround, not solution.
Overall, agree link to same artboard for a component containing links (like a left nav) would be helpful. Set the links once, then place the left nav on the artboards without editing.
