Actionscript 3 :: Save A Shape (or Sprite) To A Folder After Creation?

I am trying to create a county map of Illinois using x,y coordinates from a shp file. I have the x,y coordinates and the county names saved in a CSV file that I have no problem reading in via ActionScript 3 (and the map looks great), but in order to save time in my future application I would like to save each county shape as a permanent shape in my application and give them labels, i.e. Sprite1 (label='Champaign').

In case this is not possible I am trying an alternate solution: I create a new sprite (var spr:Sprite = new Sprite();) for each county, draw it using spr.graphics.drawPath, and give it a name (spr.name='Champaign') and then 'push' it to a vector of sprites (var xy_sprites:Vector. = new Vector.();). This would be great, but it doesn't work when I try to loop through each sprite in the vector and add an EventListener to that Sprite to pop up the name when you MouseOver any of the counties. Is the Sprite data type not the correct way to go about this or am a missing something about Sprites?

Some of my code to draw the shapes and save in a vector:

function drawXYMap(str:String):Vector.<Sprite> {
var arr:Array = str.split("
");
var xy_Sprites:Vector.<Sprite> = new Vector.<Sprite>();
