How can I call any function in a chain of functions, without the chaining?

Question

Sorry if my question wasn't clear enough. I'll put my code here...

var chain = {
    'fn_1' : {
             //fn_1 code here
             chain.fn_2();},
    'fn_2' : {
             //fn_2 code here
             chain.fn_3();}

...and so on
}

Let's say if i wana call chain.fn_1(), is there a way I can do that without calling chain.fn_2()?

What I can think of right now is a flag, but that would be alot of excess flags probably for each function. Do you guys have any ideas?

var chain = {
    fn : ['fn1', 'fn2', 'fn3'],
    call : function(name) {
       var i = 0, pos = -1, l = this.fn.length;
        for(i = 0; i < l; i += 1) {
            if(this.fn[i] == name) {
                pos = i;
            }
            if(pos !== -1) {
                this[this.fn[i]]();             
            }
        }

    },
    fn1 : function() {
        alert('fn1');
    },
    fn2 : function() {
        alert('fn2');
    },
};
chain.call('fn1'); //chain
chain.fn1(); //single
