New Exchange Admin Center -> Mailboxes - Add column for Manager

(Uservoice is gone so I guess this is the right place to post my suggestions?)

On this page:

https://admin.exchange.microsoft.com/#/mailboxes

One can 'Choose Columns' but I would like to see Manager (of the mailbox) to be shown here.

When a manager quits our company, I am currently forced to use Powershell to see what shared mailboxes I need to change the Manager-field for. I would like this in  the GUI please.

Now everybody, help upvote this! (. .  .oh right. . Not uservoice anymore)
