Can transitions be added to a source code that uses `includeIn` and `excludeFrom` to show/hide elements? It seems that elements are hidden immediately not allowing enough time for the transition to be played.

In this [documentation article](http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7fab.html), a method with `visible` and `includeInLayout` properties is used but that would mean I would need to rewrite my MXML code which I'd rather avoid.
