Organization of the codes generated by WindowBuilder

I'm using WindowBuilder to draw the graphical interface, but there's one thing that's kind of boring in it, which is as follows. When I create a JLabel for example, it declares the JLabel inside the constructor, making me unable to use it directly in other methods. Is there any way that automatically everything I create goes directly to the class, gets organized at the top, so I do not have to do this manually with all the components I have to handle in more than one class?
