I realize this is an old question, but the answer is from 2012 + there may be some more people out there that need to know this.
We at eVeliko managed to create a module that allows you to transfer controls from one page to another (template to template, and page to template are being currently researched). As easy as copying it from the source page and pasting it to the target page.
The module takes about 3-4 minutes to install on Sitefinity and is ready for use. No complicated install. Just place 2 files in the bin folder and that's it.
It works for free on localhost and costs 49 USD / domain in case you decide to use it in production.
Here is the link to Copy.Paste.Done in the Sitefinity marketplace:
Copy.Paste.Done - easilly copy controls between Sitefinity pages.
You can also contact us through our website ticket system in case you need some time to use it on a production server.
Hope this helps,
