Add a primary date filter for all websites on the dashboard.

Describe the feature or enhancement

To view traffic for the last 30 days for all the websites on my dashboard I have to set them one-by-one. Please add a primary date filter so I can set the date range for all websites at once. This will help me compare traffic between the websites.

We will be completely rehauling the dashboard and it will support this use case.
