Appending functions to an onEnterFrame

programming flash
1

if i have a function attached to a movie clips onEnterFrame, can i somehow add another function to be executed, in a way that doesnt replace the old function…

sort of like


my_mc.onEnterFrame = function():Void {
    trace("function 1");
}
my_mc.onEnterFrame += function():Void {
    trace("function 2");
}

but obviously that doesnt work :cross-eye
