When providing feedback or validations for data in the Review stage via Data Hooks, you have the ability to highlight a cell as either an Error, Warning, Comment, or Info. If a cell is marked with an error, it will be highlighted as a row that a user should resolve before submitting their data. For more information on how to configure these, please see our article on Helper Methods in v3 Data Hooks.
At this time, if a cell is highlighted as a warning , comment, or info but the user would have to scroll to the right or down to see it, there is not a way to let them know they should review that cell before submitting their data if they haven't scrolled to review all their data. This is applicable to all of our products. This also means that the cell cannot be added to the "Errors" filter in Portal 3.0 or Workspaces.
