I was asked to create a dashboard which have this feature:
the first page must contain a multiple list of slicers in order to filter data in others pages.
I don’t want to use the Filter pane but I want really a page with only slicers which filter ALL pages.
As Brian already answered. The quest you are on is for sync slicers. From personal experience and I would rather also add, good practices, when you do look into the sync slicers, pay close attention to the advanced features. This allows you to group visuals and allows for reactivity based on the current selection.
I use sync slicers in tandem with edit interactions to produce user controlled interactions.
