Hey @rubab, This is not currently available in Looker. It's definitely something we are going to do and we are actively scoping it. There is a workaround that may get you part of the way there. You can add an HTML link to the dimension such that a user can select a link and inject the dimension value into the dashboard filter. In your example, this would filter all 4 charts by the selected dimension value. You can read about how to do this here.
There are clearly limitations to this workaround. We are working on the full solution and will keep you posted.
