I thought this was the solution as well, however it doesn't work in my instance. You can do CTA (Beta) > CTA View AND Form submissions, but if the form relates to multiple content types this won't work.
In our case, we use one 'Content Download' form and filter based on page submitted to know the type. You can see how this would become terribly redundant with CTAs.
Looking for an option to view form submissions on 'x CTA', or similar solutions!
