Are there any plans to support entering in a comma separated list of app/web map IDs for the Map Tour and Map Viewer templates? The current method of selecting multiple apps/maps via a search string does not guarantee that the search results will always be the same.
The best part of using a search string is that the content changes!
Imagine I have 5 maps of Melbourne and I have tagged them with 'Hannah's Maps of Melbourne'. Then I create my Map Viewer app using the tag in my search string and push it to the app stores. All good?
But then I create another 5 maps of Melbourne that I want to add to my app. I don't need to rebuild my app - I don't even need to update the version of my app in the app stores. All I need to do is tag the new maps with 'Hannah's Maps of Melbourne', and they will automatically show up in my app!
This is a simple example, but you can also use the map publisher, item id's, published dates, ArcGIS Online groups or any combination of the above to build a more robust search string. For more information, see Use search—ArcGIS Online Help | ArcGIS
You should be able to build a search string that includes the id's of your maps using this approach. This should ensure that your app content is always the same. E.g., id:12345 OR id:54321 OR id:56789
