If you have a navigation element like a header or footer that you are constantly changing and you want it to update simultaneously across multiple artboards is there a way to achieve this in Illustrator?

I thought an AI template would be the way to go but it just seems to place an object with a wireframe without rendering any artwork.

Pasting on all artboards comes pretty close, but requires you to manually run the feature every time and pastes a duplicate over the original.

Thanks in advance for any help on this.
