Linkage Name

Hi Folks i have a question,
hopefully someone can shed some light

i have 10 movieclips in library with linkage name btn1 to btn10
so i wanted to add them to stage dynamically, so i use the below for loop

for (var i:int = 0; i < 10; i++){

var newBtn:MovieClip;
if(i == 0){
newBtn = new btn1();
addChild(newBtn);
}else if(i == 1){
newBtn = new btn2();
addChild(newBtn);
}else if(i==2){
newBtn = new btn3();
addChild(newBtn);
}
//vice versa

}

just wondering are there any simpler way to do this?
thanks in advance guys.
