Have floated this idea before but I'm so tired of wading backwards in time for ideas that were probably merged with unrelated ideas, voted up, status changed to 'liked' or 'working on it', and still never implemented, I'm just reposting them from now on.
THE ISSUE:
If you set up an Email report in analytics, and set the date of activity to be a range like last month or last year or set up a custom date range that ends in the past, the report range only ever honors the beginning of the date range. The last activities of the report always run all the way up to the present and ignore the end date of the established date range.
