How about a global script editor, in which you make a script, that automatically applies to all the actors.
For example you have got two variabels: xstart and ystart. You don't want to open many actor control menues to set the variables to each actor. You could just open that global script editor (actor create event) and write the script down once.

hm, one primitive way how to do it, just make one actor that contains the script and then let all the other actors inherit his script.
