how to group function calls for consecutive execution in jQuery?

I have a number of jQuery animation effects applied to certain elements on the page. Right now my code looks like this:

jQuery("#bgd_balance").animate({backgroundPositionY: "0px",},800,"swing");
jQuery(".balance_left_box").delay(2000).slideDown(200,"easeInCirc");
jQuery(".balance_left_box p.first-line").delay(2400).slideDown(600,"easeInCirc");
jQuery(".balance_left_box").delay(1000).animate({height:"270px",top:"64px",100,"easeInCirc");

the problem I'm facing is that when I'm tweaking delay of a certain element, i have to go through everything and adjust all other delays accordingly.

Is it possible to have something like this instead (pseudocode):

queue.add(
       delay(2000),
       jQuery(".balance_left_box").slideDown(200,"easeInCirc"),
       delay(2000),
       jQuery(".balance_left_box p.first-line").slideDown(600,"easeInCirc");
       delay(1000),                         
       jQuery(".balance_left_box").animate({height:"270px", top:"64px"},100,"easeInCirc");
).run();

I hope the code speaks for itself.

I know I can achieve this "queuing" by adding callback function to animate() call but then resulting code will be really bulky and hard to read IMO.

You might want to look at my answer on Can somebody explain jQuery.queue to me as well, but here is a quick example of how to use a queue on an empty object to make a pretty straightforward queue: 

var tempQueue = jQuery({});

tempQueue.delay( 2000 );
tempQueue.queue( function( next ) {
    // note using the callback on the animation to call the "next" function in the queue
    jQuery( ".balance_left_box" ).slideDown( 200, "easeInCirc", next );
});

tempQueue.delay( 2000 );
tempQueue.queue( function( next ) {
    jQuery( ".balance_left_box p.first-line" ).slideDown( 600, "easeInCirc", next );
});
tempQueue.delay( 1000 );
tempQueue.queue( function( next ) {
    jQuery( ".balance_left_box" ).animate({
        height: "270px",
        top: "64px"
    }, 100, "easeInCirc", next );
});
