"Group" animation events in jQuery

Problem
I have a number of jQuery animation effects applied to certain elements on the page:
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):
I know I can achieve this "queuing" by adding callback function to
jQuery("#bgd_balance").animate({
backgroundPositionY: "0px",
backgroundPositionX: "0px",
'background-size':'100%'
},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.

queue.add(

animate() call but then resulting code will be really bulky and hard to read, in my opinion.Solution
The way I see it, you have 2 options; either use Deferreds, or store your delay in a variable:
var delay = 0,
$left_box = $(".balance_left_box");
$("#bgd_balance").animate({
backgroundPositionY: "0px",
backgroundPositionX: "0px",
'background-size':'100%'
}, 800, "swing");
$left_box.delay(delay += 2000).slideDown(200, "easeInCirc");
$left_box.find("p.first-line").delay(delay += 2400).slideDown(600, "easeInCirc");
$left_box.delay(delay += 1000).animate({
height:"270px",
top:"64px"
}, 100, "easeInCirc");Code Snippets
var delay = 0,
$left_box = $(".balance_left_box");
$("#bgd_balance").animate({
backgroundPositionY: "0px",
backgroundPositionX: "0px",
'background-size':'100%'
}, 800, "swing");
$left_box.delay(delay += 2000).slideDown(200, "easeInCirc");
$left_box.find("p.first-line").delay(delay += 2400).slideDown(600, "easeInCirc");
$left_box.delay(delay += 1000).animate({
height:"270px",
top:"64px"
}, 100, "easeInCirc");Context
