To add some detail on this: the main use case is batches that are already sitting in 'awaiting review' status but were loaded against the wrong client within a group. Right now the only fix is to reject/delete the batch and rebuild it from scratch on the correct client, which means re-adding every payment line manually.

What would solve this: an option to move/transfer an existing batch (with all its payment lines intact) from one client to another within the same group, while it's still awaiting review or approval - rather than having to recreate it. This would save significant time for bureaus managing multiple clients in a group where mis-loading happens occasionally (e.g. wrong client selected at the point of creating the run).
