Extends, can i extend multiple classes?

1

I have a class with both “import flash.display.MovieClip” and “import flash.media.Sound;”.
If I do “public class SoundMove extends MovieClip” then I get errors because I didn’t subclass flash.media.Sound. If I do “public class SoundMove extends Sound” then I get errors because I didn’t subclass flash.display.MovieClip.

Is there a way to extend both MovieClip and Sound?
