One Prompt or Filter for all reports on a dashboard

Description - Allowing filtering a dashboard of reports by presenting prompt or filter at the dashboard level, that could apply to all of the reports on that dashboard.

Why is this feature important to you - It would eliminate the redundancy of selecting same prompt/filter criteria for teach individual report and then running every single report based on that same criteria, specially when number of reports on a dashboard are more than a couple.

How would you like the feature to work - I would like to have the option to allow certain fields that apply to all reports on a dashboard to show either as prompt options or filters to appear on top of a dashboard and when I select the criteria the prompt or filter apply to all of the reports on the dashboard.

Current Behaviour - prompt/filter can only be applied to individual reports on a dashboard.
