How to callback at the end of a group of animations

[bseddon]

Is there a standard way for a callback to be executed only when all members of a group of animations have completed. A callback can be executed at the end of a specific animation so manually I am able to arrange for some kind of 'groupcomplete' event to to execute. But is there a standard/built-in mechanism to accomplish this task?

There is not a groupcomplete event or anything, each animation is separate from one another.
