Drop & drag in a symbol not at frame 0:00

Hi there,

I've viewed this awesome tutorial on drop and drag ( http://www.youtube.com/watch?v=u4R8jFI_DeE ), but I want to have a drop and drag that's within a symbol and that doesn't appear until later on in the timeline.

Is there a way I can do that?

(Sorry i'm new to creationComplete)
