When emailing a dashboard, please add an option to retain current period of time

Very often I change my dashboards date and download them, the only problem is that just nearly as often the download is slow so it reverts back to emailing the report.  When doing so, the period of time that gets picked is the one which was preset on the dashboard though. So the whole exercice becomes pointless.

There should be an option to force the current timeline when emailing a dashboard.
