Possible to review past answers?

Hi! I'm using H5P on a WordPress site, and I wonder if there's a way for users to view past saved submissions? I'm thinking in the context of giving a reflective question to come back to later, or reviewing a question done yesterday kind of thing. 

I know that I can see some statistics on my back-end, but I'm looking for a way for users to go back to past work on the page. It's OK if they have to log in or something (or tie into another plugin?) to do so. 

Alternately, I noticed that there is at least one question type that generates a downloadable file (I think)  from the submission - are there others where a user could manually save their work in this way? 

Thanks!
