  # Used for RVI cDNA XP plates. Used for a custom 'Manual Transfer' state transition.
  # N.B. 'Manual Transfer' is used for the RVI BCL pipeline for the cDNA XP Plate because the plates
  # are inaccessible in the bed at the time of transfer so cannot be transferred via
  # bed verifications. Also we cannot set its state to 'Passed' on initial bed verification
  # because there are steps on other plates that need to be completed before the cDNA XP Plate can be transferred.
  # and we do not want to misreport the plate being passed if an issue arises with the steps before hand.
