Mass template editing?

[Gaussian]

Maybe someone can create a hack where you can mass template edit, example:

Lets say I want to install a Quick new thread box. I edit my .php files. Then I go into my admin panel. But I don't wanna have to go to every single forumdisplay template and add the coding. Nor do I want to add a new template manually to every style I have. So I use the Mass template edit hack to add the Quick replay box template to all of my styles to to edit all the forumdisplay templates in all of mys styles.
