How to duplicate button with the AS?

see i have this project where i need a number of buttons with the same function throughout the flash.

i tried dragging them to the stage from the library, but the problem is i have to copy the AS over and over again, because i’m ASing on the main timeline, i have to give instance name to everyone one of them.

is there an easier way to do it?

i’m thinking script it using the linkage name rather than the instance name but i don’t know how to do it, but that’s just a thought.

feel free to hammer me with other guidance and thanks
