It would be great if field workers were able to download and set offline basemap areas themselves for use in Survey 123. Something similar to the functionality in Field Maps or Sweet for ArcGIS.
I have over 100 field workers using any of 50+ surveys in various locations. To set an offline area for each survey for each person would end up being a full-time job and would require a web map created bespoke for each survey or each user to avoid having too many areas inside one map making it difficult to view/search.
Being able to have a setting in s123 in the home page to select and download their own offline areas for use across all surveys on that device would make it a lot easier for individuals to manage and massively reduce storage space on their devices
