Easier Tab control?

[Mr Freeze]

Hi, I have an application with many tab controls (and in many of them I have other sub-tab controls) and I feel that it is heavy/troublesome to create new tabs or to maintain the existing ones. Is there a way where I could just edit new tab controls visualy without having to create a new dialog for its content everytime? I imaging being able to add a tab control to my dialog. Then I would simply specify the labels for my different sheets and by clicking a specific label, its content would be displayed and editable. Now I always have to create a new dialog for every tiny sheet, then programatically set up everything and see the result only when running the application. Thanks for your help :)
