Have Web Apps list which Web Maps they reference on Item Details page

I'd like the Item Details page of Web Apps to show which web maps they are referencing. In web maps, it shows which layers the map is referencing:

It would be very helpful to have a similar view of web maps in each app's details page. I often find myself searching for that information, and instead of having to dig into the edit mode of the app, it would save a lot of time to see it right there.
