Hi Ronald,
With 2 steps in a workflow built with Gravity Flow you absolutely can do this with ease. I put together a quick walkthrough video showing how it combines the use of conditional logic on some html fields tied to the total score, our Form Connector extensions’ Update Fields step type to map the likert score into a number field, and having the forms’ confirmation redirect to an inbox (shortcode or block) that uses an approval step for the appropriate html fields get displayed.
I would expect you’d want to do some further customization around CSS/theme so that the result/landing page for the confirmation redirect looks less like the approval screen with how you describe your survey. But it could also be a stepping stone to engage the customer in other follow-up action. At the end of video I cover a few options like using the expiration setting to limit how long they could review their answers/result/etc.
Hope that helps.
Jamie
