You can do what you want.
Ideally - you would start to use movie clips as buttons as you can do much more with them.
If you have an instance of something in the library - right click on the library item and choose duplicate. Any actionscript contained within that item will also be duplicated.
It depends on what you are doing or plan to do. Sometimes it pays to have seperate functions for each button and call those functions from the main timeline. (not forgetting to give each movie clip an instance name in the properties field.) But you can basically do what you want. Movie clips as buttons will give you more scope.
