Feature request: Automatically place markers in the timeline at points where the speaker changes

It would be hugely helpful to have the option to automatically have a marker placed on the timeline to indicate when the person speaking changes from one person to the next. This seems like it would be fairly easy to implement, particularly with the current AI captioning system. As someone who produces hundreds of interview clips a year this would be a massive help that doesn't seem like it would be all that technically difficult to produce. PLEASE MAKE IT HAPPEN!!!
