ActionScript 3.0 :: Enable/Disable Group Of Filters?

I was wondering if its possible to add an array of filters to a movieclip, then remove the ones that correspond to another array.At the moment, I can add the filters to the array with concat but there doesn't seem to be anyway to reverse that.I think it's easy to show what I want to do with code:

Code:
var filterslist:Array = new Array();
var filters1:Array = new Array();
var filters2:Array = new Array();

[code].....

/* hover out: (what I want to to do but no function seems to exist): */

filterslist = filterslist.removegroup(filters3); // think of it as an inverse concat function
this.fitlers = filterslist;

I think it may be possible to do by looping out the filterslist array, sub-looping the filters3 array and then comparing each one and splicing it out if they match but this seems long-winded, bad code and would produce bad performance.
