InfoPath Dev

How can I move more than 1 field at a time to a new group in the Data Source?

I believe you can only move a field or a group at a time.

Unfortunately, this is a pretty big limitation of the InfoPath Designer.

If you want to get crazy you could manually edit the schema files, but this can be very meticulous and would probably only be worth your time if you need to move >100 nodes to a different group.
