A suggestion that I thought might be helpful:
When you create a few elements for the same page, for example you add a specific hook AND you also change layout (remove sidebar for example), these are done with 2 different element types: Hooks and Layout.
My suggestion is that there will be a notification on both layout types, notifying that there is another type applied to this page with a linkg to that specific page (kind of like the links in the customizer: colors, typography etc’). So in case you have a long list of elements you would know that a page has a few of them applied to it.
