Build Mode Feedback for EA

@aquilifer I think a function like that would be very helpful, and I'll add your request. One thing you could try in the interim is to save your structures as rooms. If you do this before you've detailed out the interior (or temporarily remove interior walls), you can pretty much save each structure and then add it to a different lot from your Library. You do have to save each level of the structure separately too, but it's easy enough to place them back on top of each other on the new lot. Saving a room will not save any roofing, so that's probably the biggest negative of it. However, from my testing, saving a room does preserve other stuff on the exterior, like windows and shelves. So you could do a good bit of detailing on the exterior prior to saving it and not lose much of it.
