Campaign Style Map Markers in Editor?

[Wellington007 1]

So, this may be a simple answered question, but I was wondering if you could make the map markers in Eden Editor similar to the ones in the campaign. 

Like this. It would really be cool and add some more immersion. If anyone has any work around, mod or way to do this in the .sqm/folders let me know. It may be impossible but its worth a try.
