Is there a way to change background art in Echosign?

We recently updated our logo and are trying to get all of our forms to match. That said, is there a way to just update the background art on the existing documents? Or do I need to replace EVERY single document with a new widget revision? That said, is there a way to COPY the existing form? (Most of the items do not have a library template and I cannot simply use the old template... )

For reference here's one of the item's we're trying to update our logo on.

Thanks for any help you can provide.
