The Web App Builder has a GeoLookup tool that allows you to add a CSV file containing addresses and look up up to 10,000 addresses at a time. This is a very useful when working with light datasets.
With the Web App Builder being deprecated, Experienced Builder seems to be the natural replacement. However, the Add Data widget in Experienced Builder which also allows you to add a CSV file containing addresses currently only supports up to 1000 addresses at a time. From a user perspective, this feels like a downgrade in functionality, especially for organizations that rely on this tool to process thousands of addresses.
I would suggest adding a dedicated GeoLookup/Address LookUp widgets in Experienced Builder that can accept csv file (or other file format like pdf) uploads and process thousands of addresses at once. At minimum,10,000 address capacity that was available in WebApp Builder, or if technically possible, an even higher limit would be even better.
