Unfortunately the sentiment column is just a number from 1 to 5, so you wouldn’t be able to change it with the settings I proposed. Additionally, that’s not user dependent, so each user would have overwritten the previous one’s rating.
There are several ways to solve this, but by chance i have recently proposed a solution that also fits here. Take a look and let me know if that helps you
I’m assuming your ‘articles’ are in a table, similarly to the ‘playbooks’ in the example from the link. In that case you would need to create a new table for the ‘ratings’.
If each article is on a different page, then the solution will have to be more complex.
Can you share a dummy doc or provide more information about your use-case?
