At the root of your site tree go to Sub pages and Create new page. Make sure to check Hide in navigation. Note: only top level Pages can be hidden. Name it Clipboard or something easily identifiable. This Page is still going to be accessible on your site, but since nothing will link to it, this should not pose a problem to you.
Since when you use the Copy/Paste buttons in CP5, every time you Paste, you are actually creating an instance of the original object. Change it in one spot and it changes globally. Now you can place your objects inside a splitter inside a splitter, and still get to them easily using your new "Clipboard."
