Say I have 3 checks in different regions of China
And I have 2 derivatives of these, so 6 checks in Total.
Well if I want to use them in Analyse Metrics, then I can do. But it's impossible to see which chinese check I am selecting. Rolling over the flags anywhere in this screen doesn't show a tooltip like it does on the Dashboard. So effectively you have to rename checks to know where they run from.
Even with the rollover when exporting the graph it would be unclear which check was which within China. It would be useful if you could say whether you expect users to put the name of the location into the check name as this seems to be the only workaround at the moment.
This idea has been promoted to a feature.
