Is there a way to get the brush stamp to align with the tip of the Apple Pencil when e.g. using tilt to drive the size of the stamp? It seems that the stamp is scaled around the center point, so when using a brush that emulates drawing with the flat of a pencil, the stroke output is very hard to predict. Also with asymmetric stamps this is a pretty obvious problem.
To see what I mean, try drawing with the "graded charcoal" brush and see where the hard edge of the stroke lands relative to the pencil tip.
