No. I think it's the same like in the agenda item view: projector button on the top shows the agenda title. An extra button (with description "show list") show the special slide "list of speakers" as a part of the agenda item. So I like to use in the top right only generic buttons which are related to the object (motion, item etc.) for a quick switch to the object slide. And special slide view can be activate with a special projector button in the content area.
