Hi Dean,
You may be able o use a resource file that a repeating table/group can pull data from. If you create an xml file with the data in it, then you could include it in the form by attaching it as a resource file and referencing it with a secondary data source connection. Then you can filter the values based on your needs.
I have had success with this method in the past, and you can transfer the form outside your domain without losing functionality. I hope this helps !
