You can also add another roof over the top with adjusted lollipops or a shed dormer offset correctly (use walls or beams set not to extract and offset so that roof material is the only thing showing while turning off everything else), or use a beam with unique material and size set to fit to roof then offset, or use a ceiling and offset over the top of the double hip. Depends on the shape of what you are trying to cover and how much adjusting you might do. It may take a bit of work, but could be less hassle for how the fascia and soffit align with one double hip roof system and something added on top for the different roof material. If using SoftList it may get confusing, but works well often (and can be set to turn off in certain modes or views if desired.
