Recreating Rake Board Overhang

[ChiefDXS]

My boss has told me to create this house in Chief Architect with only Auto Roofs that way if the dimensions are off, he can change them later. Here is a link to the house's listing: https://www.zillow.com/homedetails/110-Fox-Chase-Hendersonville-NC-28739/441854964_zpid/?

I have completed the creation of this double Rake board on this side of the house:

However, on the other side, I have to create another overlapping Rake board:

Creating a full gable wall on the side of the house does not work for this side, because the second story is in the way:

If this were completed, I think it would change the other parts of the roof, and probably complete the plan:

Does anyone know how to create this with only Auto Roofs?

Also, many thanks to Jonathan K and y-g-m-n for helping me get thus far!
I know this would be easier to manually tweak, but in a few weeks my unpaid internship comes to a close and my boss wants to be able to easily edit the plan with any updates after I'm gone.
