My Pages - Admin Overview

I see that the My Page feature has picked up significantly at some customers, particularly with worksheets. Yet, as an admin it's a great trouble to understand the impact of changes to these personal pages. Today it is only possible to see the number of "My Pages" created by each model.

As a Workspace Admin, I want an overview of all worksheets / boards that have My Pages created so that I can assess the impact of any structural changes to the underlying modules. It also helps to understand which worksheets / board are the "very popular" ones.
