Hi Bob,
In fact, my first banner on the page is full width.
My description might be not clear, so let's use picture 
In the following example, here is what I try to achieve.
Currently, article 3 jump over the Divider banner. So to resolve that I create a fake banner, invisible.
It works, but then If i update my main collection with let's say 2 new article I'll have to add a additional invisible banner, which is painful to maintain.
I spoke with other colleagues editing in AEM, and they found the same fix. Any idea? or let's put that into a wish list...
What want to achieve
