Yeah pretty easy, just create a facade stamp ! Follow these steps and use image as reference.
1. In section create morph elements as per your facade material "split"
2. extrude morph by a bit, my example 1 meter
3. move morph elements to overlap wall by 1mm and use SEO. ( make sure on new target surface to use inherit from operator )
4. Hide layer with morph on it = Result !
