将通过编辑器添加的动画片段带到前面

I have a game in which I have three different scenes. In the first scene, the objects (movieclips) were added through the flash editor, meaning that no actionscript was used to add them (not added with addChild). After that ive decided that I want to do the second and third scene entirely through actionscript and every object that is added is added with addChild(). The problem with this is that now the objects that have been added through actionscript appear in front of the ones added manually through the editor and I want it to be the other way around. I know that addChildAt() exists but I have over a 100 objects so it doesn't seem like a good option. In short: How do I set the Z-Indexes of movieclips that have been added through the flash editor and not through actionscript.I have a game in which I have three different s
