How to place variable/drop-down in Grafana dashboard header permanently?

Hi Team, Prometheus data source allows to use a query variable label_values(metric) and to place it in Grafana dashboard header permanently alongside with annotations. Which is exactly what we need and what we are happy to see. Is it possible to achieve such result not for Prometheus only? Is it possible to place Business Variable in Grafana dashboard header permanently? We need it to be there permanently even if a panel is used in “View” mode. Many thanks!
