Hi. We are actively working on this. Essentially, we are planning to add support for geosearch in the map widget against online locators. Initially, the geosearch capability will not be enabled while working offline. On top of the geosearch capability, which will let you center the map through an address or placename, we also want to extend the pulldata() function so you can extract the address or placename that the user entered and store it as an attribute.
The above will not be part of 2.6 (late January), but could make it in 2.8, or may be even 2.7 (At the very earliest). If you would like to try the geosearch experience, you can download the MyUSNG app from the Google Play, Microsfot or Apple app stores:
* MyUSNG - Android Apps on Google Play
* MyUSNG on the App Store
* Get MyUSNG - Microsoft Store
We are using MyUSNG as the testing ground for the geosearch capability. More info on MyUSNG here: https://community.esri.com/groups/appstudio/blog/2018/01/10/myusng-now-available-in-windows-store
