Batch Operations to support Connected fields

It would be really useful if batch operations supported the ability to update connected fields. This would be particularly helpful when migrating data into TB. I’ve had to repeatedly re-importing the CSV file into the connected field value (as I’ve setup new tables) and when you have a lot of records (100,000) I’ve found I have to split the CSV import into smaller files. It would be so much easier to just just “copy” the existing related field into the newly created connected field in one go.
