Kelly - Thanks for the reply. Its good to know that those 2 instant apps are more functional, I'll have to try them out again. I didn't try the Nearby app, just the Zone Lookup.
With regard to the storing location functionality, the Information Lookup app allows you to use both, so we set up a layer representing addresses of locations but also use the esri world locator. Thank you for considering this option, I hope your team is able to find a way to include it.
