Can you add and remove SPECIFIC overlays/itemized overlays?

Essentially I have two overlay classes, one is used to draw a route on a map (should be visible always) while the other is used to display the current position of the user as given by GPS and shown by a small cursor on the map. Each works good by themselves but I cannot get it to work together.

I can only see

-getOverlays
-clearOverlays
-addOverlay

Thereby I can only create one at a time. I know with itemized you can delete certain ones but like I said I always want the route overlay to be visible and be able to draw the users current position with a cursor then when they move, remove that overlay and replace it where they are now all the while the route overlay exists.

Before I pour anymore time into this, can anyone let me know if it is even possible?

Looking for something like: (just pseudocode0

Using java Syntax Highlighting

 
//REMEMBER JUST PSEUDOCODE
 
MapOverlay mapper = new MapOverlay();
 
CursorOverlay cursor = new CursorOverlay();
 
add(mapper);
 
add(cursor);
 
invalidateMapview;
 
Upon a location change{
 
      List overs = getListofOverlays();
 
      overs.remove(cursor);
 
      cursor=new CursorOverlay() <-based on current location
 
      overs.add(cursor);
 
      invalidateMapview;
 
}

THANKS IN ADVANCE, would love to find out if possible or not.

Also with this, I need to be able to have two different route overlays show up on the screen (which I have right now) but the second will need to be periodically deleted and redrawn. Again , the original route overlay will exist for the lifetime of the activity.
