MapMarker from a BufferedBitmap rather than a resource

Is there any way to use a Buffered Bitmap, rather than a resource, to set the icon for a MapMarker? I just want a range of different colored square and circle symbols and hate to create a bunch of icons just for that. Creating them at run time would be much cleaner here.

Currently, the only way to get access to the BitmapResource that backs a BufferedBitmap, is to initialize it from a BitmapResource.

I think you could create a single resource that was a blank canvas and load it multiple times, initialize BufferedBitmaps from it, and then draw to that surface. I believe the VM will load a separate copy of your resource every time you call WatchUi.loadResource().

Brian, your a genius! Works like a charm.

for(...)
        {
            var res = Ui.loadResource(Rez.Drawables.MarkerDkBlueDot);
            var bbm = new Gfx.BufferedBitmap(
                {
                    :bitmapResource=>res
                });
            var dc = bbm.getDc();
            dc.setColor(tracker.clrDog(iDog),ClrTrans);
            if (sym == SymMoving)
            {
               dc.fillCircle(8,8,5);
            }
            else
            {
                dc.fillRectangle(2,2,12,12);
            }
            lst= res;
        }
