Unified "Sent" mailbox in Mail (or any other mail application)

[neartheredrocks]

Hello,

I miss to have a unified "Sent" mailbox in Mail on my iPad, similarily to the unified "All Inboxes" mailbox. It makes dealing with mails from different accounts very cumbersome.

Can Mail be configured to show such a unified sent mailbox?

If Mail cannot do it, is there any other iOS mail client that can?

Thanks - neartheredrocks
