Please yes. This is something I wish for on a daily basis. I have thousands of pages of diagrams and sketches in Goodnotes, and I often use the highlighter for grey shading to convey a 3D shape.
Currently, I have to carefully draw the entire structure in one go, without raising the pen, because if add 2 highighter strokes together it shows much darker where they overlap.
Having to draw an entire shape in one go is much harder and more time consuming than being able to draw it in multiple tries.
Having an option of whether to 'stack' or 'merge' highlighter strokes would be a godsend. Please add this!
