Hi there @gt3 and welcome to our Community!
The best way to think of Zapier is “when X happens, do Y” - so to answer your question in short, it wouldn’t (without a buncha custom work) be easily possible to create a one-stop dashboard of performance metrics across Instagram, Twitter, LinkedIn and so on.
However, there are a number of platforms that do provide those dashboards, a quick search showed a promising one called Geckoboard that offers a free trail (we aren’t associated with them, just looked like what you may be looking for): https://www.geckoboard.com/dashboard-examples/marketing/social-media-monitoring-dashboard/
Best of luck in your quest, and come by any time with other questions you may have. Best -Rachael
