How can I use an existing page selector in a dashboard, to filter a line item that is using the same list? I have created a module that uses a country list as a dimention. Then, I created a dashboad to pull this module and used the same list as page selector. Now I have created an other module, but on this module I am using the same country list data line Item. I am planning on addidng all of them on the same dashboard, how can I do that?
