[mkgmap-dev] Has anyone built NO-LEFT icons like the way JOSM shows them?

JOSM shows individual NO LEFT turn icons at the right side of each intersection, if it is set It seems to me I would have to make 4 separate TYP symbols and lock my GPS in NORTH-UP mode to keep orientation. I would also have to place a small NO LEFT turn symbol in each quadrant of each TYP symbol and only use the appropriate icon. I just do not know how to write the code. Has anyone done this? Greg
