See what I did in the attached.
On the two sheets on Dashboard1, I removed the Company filter. And instead I made the action filter applied to both those sheets. Then I exposed the action filter on Dashboard1.
So when your user gets sent to Dashboard 1, he sees the company that was selected on Dashboard2. And the filter is set with that one selection. But it's there to modify if the user wants to see something else, and that one filter controls both sheets.
