When unblocking a mailbox, have messages automatically placed in the inbox

Currently, if you block a mailbox, all the messages (and the mailbox itself) go into the "Blocked" folder.

If you unblock the mailbox, new messages will go to the Inbox, but these old messages stay blocked.

I would like to see these messages automatically go back to the Inbox, or at least be given the option to move them to the Inbox or Saved folders.
