Not really. You might consider using the Convert to Seperation Model method to minimize the need for imports. With that method, you have two files--one holds the data and the other the interface. When you change the interface file, you can send the new copy to the user and they replace the old copy with the new and do not need to import any data.
When importing data can't be avoided, it can be scripted so that all the client does is click a button, select a copy of the old version of the file from which to import the data and then the script does the rest.
