The same filtered list at every site
Teams often need to see the same slice of cases at every site: the reviewer wants only this month's submissions, the program lead wants only the commissioning reports, the M&E officer wants only cases with a particular tag. The CASES tab lists everything ever submitted at a site, so each of them ends up rebuilding the same filter, site after site.
A Site Custom View solves that. A manager defines the filter once for the project, and it appears as an extra tab beside CASES on every site's dashboard — RECENT SUBMISSIONS, say — already filtered.
