Rust Map icons (paid $$$)

Any sort of ability to use icons on the map in addition to the paint style editing? like a simple house outline matching the size you select from the edit tool or something. not just house icon but anything else, like prefab "x"s, since i like to place premade maps in chests on the map that lead to a locked chest of treasure. lose the map or the key and the treasure is forever gone. :0
