Numbered markers?

May I suggest an enhancement for numbered markers? I have hacked (I use the word advisedly) the plugin’s osmap-script.php to support numbered markers, by specifying a marker “colour” in the form n0, n1, etc up to n20, and using the images at https://mapicons.mapsmarker.com/numbers-letters/numbers

I use them to associate numbered photographs with their positions on the track. They could also be used to refer to points on the route from the text of the post. For “n0” I use a marker that shows S rather than 0, to mark the start of a circular route.
