Reporting > Insight - How to see what device used data

[bunchofreeds]

I'm looking in Reporting > Insight and can't find out how to isolate what specific device used a large lump of data in a 10 minute period a day ago.
Is it possible to set a smaller time window within the 'Details' TAB, like an hour on a certain day to show usage results rather than a whole day? Then I would be able to isolate the device more easily.
