Retroactive Session Title & Speaker Names Relabeling

Voice ID and calendar-based naming only apply going forward — once you've named a speaker or connected your calendar, every new recording benefits automatically, but there's no way today to rescan your whole back-catalog and suggest retrofitted "Speaker N" labels or titles on already-processed sessions. There's no way to trigger that manually either... that would not only better label my entire library but would dramatically increase the usefulness of the AI agent when asking questions that span multiple sessions with the same people.
