Updating managers can currently only be done by uploading a new CSV. It would be a great time-saver to build an interface for admins that allows them to simply add or edit the name/email of the user's new manager from the user's profile page.
This idea was considered when developing our product plan for Q2 2019 and is not expected to influence development within Bridge at this time.
This idea will remain open for vote.
If this idea is in the top 10% by vote next cycle it will be reconsidered.
