Adobe Catalyst: rounded corners

I've created a rectangle in catalyst and under the "properties" panel, all I can see is Corners 10 for the rectangle. Is there a way to individually define each corner similar to CSS. I can't se开发者_如何学编程e any source code view in catalyst to enable me to fine tune it for each of the 4 corners. How do I specify the roundedness of each corner separately?

I think its no way you can do it in Catalyst, but after importing project into the Flex, you could adjust each corner manually by editing the CSS file.
