Issue/Introduction

How can we add an option in the dropdown for Tim Range of when a dashboard is emailed to a user ?

We would like to add "Last 12 Hours".

Can we add values to default time rage for a dashboard?

Resolution

The OOTB values are tied to timeRange=X  where X is 1 through Y, hard coded values for last hour, 4, 8, 24 hr, etc. This would be an enhancement request.
