Batch Vote on Multiple Items in a Workflow
You can vote on multiple items that are in the same workflow at one time.
If items in the workflow you are batch voting on have been updated and items are in different versions, you will be given the choice of all possible outcomes over all versions of the workflow. If the outcome chosen does not apply to all items, only the affected items will be voted on when you batch vote.
In this case, you will still need to vote on the remaining items.
