Similar to the "Update from Source" available for terrain models, it would be great to be able to right-click on a fieldbook that's being read from an external file and tell it to refresh based on edits made to the external file.

Of course, there should be a warning that pops up telling the user that any edits to the fieldbook that have been made since the original import will be lost. But this would really speed up the current process, which is to delete the fieldbook and then create a new one.
