Making a symbol effect opposite

I'm trying to use Flasheff 2.0 to take a picture of french doors and using the "Unpack" effect create the doors to open rather than close therefore doing the opposite of the effect. I have the premium Flash eff 2.0 so I'm wondering if there is a simple way of changing the code to do this. Once again I want to have the symbol start off with it being the picture and end with just the stage and not the image therefore doing the opposite of the effect. If anyone knows how to do this please let me know.

Try to use hide effects instead of show.
