The basemap used during a map tour doesn't change between the overview and a specific stop along the tour (using a custom extent rather than the default view extent). It would be nice to have the option to change the basemap that is in use at any given stop along the map tour. Many ESRI basemaps give a clean look at the full extent of the map tour but lack detail, if a more zoomed in extent is chosen. The ability to swap basemaps to the imagery basemap or one of the others (or custom / organization basemap) would add more context to the user working through the map tour.
