It Possible to copy controls on a screen to another screen in another App.
In copying controls on a screen, ensure that all connections between the two apps are same.
For instance if you have a form as part of the control being copied, then the Datasource connected to the Form should also exist in where it been copied to. Otherwise you may have to manually change codes which could be a tall order.
Having said that to copy all on a screen, simply use:
Control+A then Control+V to paste in the other App.
