Currently, for location in the UK you can select GB|England or GB|Wales etc. But it would be much more useful to extend this to cities and therefore be able to exclude large chunks of conversation coming from major cities. To exclude London, for example, we have to pull all the mentions for England, 50-60% of which is from London, and then exclude London, which makes it hard to estimate how much data we need, in order to get useful conversation insights from people living outside major cities.
The USA has state-level filtering, and Italy has region level. It would be great to improve the granularity of the UK boolean, as it is possible to filter for city afterwards, but not before pulling the full data.
