Collapsed Outlook Sidebar - possible to change displayed name of favourited Inbox?

Hello,

Is there a way of renaming the favourited Inboxes of mailboxes that I have access to via my main mailbox?

Currently, when the sidebar is collapsed they all just read as Inbox and lose the marker of which mailbox they actually come from. See the image.

Is there a way to give each Inbox a custom name that is local to this particular Outlook profile - that then persists into the collapsed sidebar? Or any other way?

Much appreciated.
