Optional mapping of spray paint markers

[CedarJack]

I think it would be great to have the option after spray painting somewhere to either map the marker or not.

My reasoning:

-I like to spray doors, cars and dead ends that I've already searched a lot but in places like Milton this gets a bit pointless having them all mapped and just having relatively redundant "multiple markers" points on the map.

- For explored or not I just use the charcoal

- I would love to mark some routes with go/don't go but mainly to have this show on the map for planning routes not so much for the actual visual aide when exploring
