Hi Dale! I can totally see how this feature is really important, so thank you for following up. As of now, you can insert a text hyperlink in the Incorrect Answer feedback area by highlighting the text and selecting Insert Link. There, you can insert a link to a web page resource, but there isn't a way to hyperlink to another lesson in the same course.
If you want learners to go to a specific lesson depending on their total score, I would suggest adding buttons like Trina does in this Rise 360 course.
If you're looking to do something different, you can also see what is currently on our Rise 360 feature roadmap. Linking to lessons in the same course is not on the list at this time, but that would make a great feature request!
