Hi @user2037 
Unfortunately, there is no option to display product reviews in our Etsy Reviews app.
This idea is really great and I’m so sorry that we don’t support it now 
We already have such a request in our Wishlist. Please vote for this feature to get a notification upon its release - Display review by products instead of an entire store
If anything comes up, please feel free to contact us. We’ll be happy to help!
Have a nice day
