Any way I can do this easier?

So I have about 340frames, what I am doing manually atm is:

Copy Frame1, select Frame2, Paste in Place Frame1 into Frame2, Select all of Frame2, Copy Frame2, select Frame3, Paste in Place Frame2 into Frame3…

etc

Then afta I’ve done this, I have to repeat this process for 4 more layers.

Is there any way I can do this faster? I know with Photoshop I could make that into an “Action” but not sure about Flash 8 :O?

Please help, my hands are breaking :frowning:
