Custom toggles for dashboards

### Problem Statement Wondering how to quickly edit a dashboard widget visual to toggle between ket metrics being tracked per widget, similar to how the Releases view shares quick adjustments for crash rate, transaction or error count, etc. ### Solution Brainstorm It would be nice to adjust an entire dashboard in Sentry between p50/p75/p90/etc. metrics. The best current approach to adjust an entire dashboard in Sentry between p50, p75, p90, etc., is to manually edit each widget in your dashboard and select the desired percentile metric for each one. ### Product Area Dashboards
