Dear all

I have developed an application using Dashboard 2 (flowfuse), and for many areas I have only one dashboard with many gauges. The operator can select the line and area. After that the gauges show the information according to their selection. I developed this way because I don't need create many panels and dashboard, it is easy to update and manager.

Problem: When other operator access the app by other browser and select other area, both dashboards change to the same selection. How can I have some variable for each instance (app opened on web browser)?  
When the operator select a line and area, has one variable (flow) with this selection, when the dashboard data are updated, the gauges just show the line and area selected.
