Only to the extent allowed by those programs, which, in many cases is almost nothing (you need to be able to name your components in a particular way in order for them to be displayed in the way it at all makes sense, you need to be able to preview the animation, states change etc.) After all, designing skins for Flex isn't the primary, nor even a well-supported option of those programs, thus the output is bloated with a lot of junk, you need to clean up by hand, which sometimes takes more time then the actual design process.
