Not sure that understood what you mean, can you show by screenshot what you mean, all is possilbe, if it is possible doing by browser, I don`t think that the version here add some change, on every version it can be possible.
I think you should be able to set up filters by sender or title in your mailbox and move such e-mails to special folder. Then you will be able to select this imap folder in zenno e-mail processing action.
