Customer wants a native ability to run switch back experiments. KFC UKIs use case is where they want to run intermittent experiments say, by time of 30 minutes using their store or (possibly transactions ID) traffic types. Today, this can be achieved using clever configuration of Admin API, targeting and scheduling but without access to measurement and analysis dashboards. I dont belive this is an urgent requirement at this stage, as need to properly speak with customer on use case and timings, vs ability to build on their side.
