Hi Samuel,
sadly there isn't a way of implementing this via Viewport out of the box.
You have to implement this by yourself.
You can add macros into the viewport template via a REST API and Javascript, so the "Yes/No Questions" would appear on every page.
In our Documentation you can find a recipe of adding a like button, which maybe comes up to your need. (if this page helped you, please like)
I hope this will help you!
Best,
Steffen
