If I want to filter a range of dates let's say between the 01/01/18 to the 21/02/18 it would be nice to see my aggregation of value between those dates. It's really cumbersome for this to only work with a filter, as I may only want to see that range once.

Also to be able to format this aggregation as a specific field like currency or time would also be required. It just seems like something that is already there but not quite work properly.
