Copy Layer automatically from the middle of one composition to the start of another composition?

Hi,

I´ve searched aescripts, the forum here, mograph.net and via google, but couldn´t find anything about this topic.
Maybe you know a script, with which you can automatically copy a layer from the middle of one composition to the start of another composition?
Right now, if the "target"-composition is too short, the copied layer won´t show up in the timeline, so you can grab it to the start...

Thanks a lot,
Oliver
