Shadow transparency following object transparency


If I add linear transparency to an object that has a dropped shadow, the transparency setting doesn't affect the shadow - it stays opaque. Please, improve the shadow behaviour, so it reflects transparency properties of an object.

I know of a workaround to break the shadow apart, convert it to bitmap and then apply transparency to the bitmap, but this workflow is "destructive" - every time I have to manually update any object changes to the shadow.
