In Exchange 2013, there are many options available when running a search cmdlet in PowerShell in particular to target those results to a Discovery Mailbox of your choice (i.e. New-MailboxSearch -TargetMailbox), but this option does not exist in the Exchange Admin Center. Allowing these options in the EAC will be helpful for non Exchange Admins, such as Compliance Officers to perform their daily tasks.
