Combining Dashboard Subscriptions and Alerts

Hello,

We have access to the Usage Analytics and there’s very helpful dashboard for Dashboard subscriptions and alerts which I would like to be able to combine into 1 single question.

The need here is to be able to look at how many notifications/alerts are sent on a given hour and while I can figure that out separately, I want to be able to look at all the alerts in 1 view.

I wasn’t able to find a way to join the two tables using the visual editor so my guess there is that it’s not joinable? This would make my life 5x better
