PASSING MULTIPLE VALUES FROM ONE DASHBOARD TO ANOTHER

Hello,

We are trying to build a dashboard. Here is the scenario, In the main (parent) dashboard the user makes all the selection of countries (typically in a list builder component). Then when he hit ok, another dashboard (child) will be triggered where they can see the charts/details for those countries. So the problem is how to pass the selections (multiple) that are made in parent dashboard to child one.

Please help me how resolve this. Thank you
