Feature Request: Per-stroke Normal blending mode (Replace/Overwrite) in Substance 3D Painter

When painting multiple strokes on the same layer, the Normal channel blends strokes in an additive/accumulative way by default. There is no brush/stroke-level option to make a new stroke replace or overwrite the previous stroke’s normal information. To achieve an overwrite result, I have to either change the layer blending mode or create a new layer for every stroke. Creating many layers hurts performance and makes the project messy; changing the layer blending mode affects the whole layer and does not solve per-stroke behavior.
