Including AS

one posibility to include a script is from external files with
#include “script.as”

i think is more faster to include from inside fla.
i have 5 movie clips and 6 buttons in each movie clip. the actions writed on the frame of each mc are the same. i want to include that in each mc from other place. can i include it from root in the same fla for example? i repeat, is more faster because i modifiy it regularly for testing and i don’t want to switch the document and then save and then go back for testing.
thanks.
