Be able to copy a workflow, as well as, save and edit an existing workflow you are planning on sending. Schedule workflows to be sent on a specific date and re sending sent workflows to an employee(s) from the original in the even that one is rejected by the reviewer. This will eliminate the potential need to have several workflows open cluttering up the Workflow Campaigns with multiple workflows that are the same.
Definitely need a way to send reminders to employees who did not complete workflows!
