AS 2.0 Array question

Flash MX 2004 added some new features to the Array.sortOn(); code. Is there anyone here familiar enough with those new features to answer this question?

Is there anyway to apply “options” to a single “fieldname” when using multiple “fieldnames”, This might make it more clear(sort within?):

myArray.sortOn([“number”, “name”], 18);

applies to both “number” and “name”

How can I apply Array.DESCENDING and Array.NUMERIC (18) to JUST “number” and still have “name” ascending (default)??

Thanks guys in advance!!!
