Ability to Pause Updates in Data Sources

Sometimes I need to move back and forth between different configuration tabs when I am setting up a data source. Every time I come back into the Data Sets tab it seems like the result cache has expired and new results need to be pulled in (even if I have not changed the configuration of the Data Source). I would love the ability to pause updates here so I don’t have to wait for results to cache. Especially during a Data Flow’s initial setup I waste a lot of time waiting for these results to come back when I don’t need them, maybe I am changing how I have stitched together various data sources into a larger joined data source, I don’t need to see most recent data while doing this.
