I'm developing a story map using the map series template and am using web maps to take advantage of the map location synchronization across tabs. The user establishes their location at the beginning of the story through an address search (though passing in url parameters would be even better ). I want to create a story action that only manipulates the content of the web map - just turns on the imagery layer, for example - but everything else stays the same, especially the current extent. Neither of the current options seem to do what I'm after - 'Map default' takes me back to the initial extent of the web map (zoomed way out), and 'Custom configuration' requires me to set one specific location that would be used each time.
Thanks in advance for any ideas you may have.
