I am still confused by your question, so you have movie clips on your main timeline that you want to stop on the last frame of each one of those movie clips so taht they do not repeat. And you want to be able to copy and past them onto the main timeline in their final state.
I think I have you wrong, but you just need to use gotoAndStop(); depending on wether you want it to go to a certain frame of frame label, reply back because I think I am not getting it.
[EDIT: Can you post the source file for me to edit?]
