Minimap Silver Arrow: Make Different for Bronze Timekeepers Etc?

Is there an Addon or something that can make the silver arrow on the minimap different for the things in the world that are constant like Bronze Timekeepers, Wind, etc.? When I'm flying and see a silver arrow I turn to see if it's Disturbed Dirt or a pack or whatever and most of the time it's a Timekeeper. I know I can mouseover the arrow but since I'm usually going so fast I have to turn to keep it on my minimap long enough to mouseover it.
