You could pretty easily use piped text to display responses in a following block, but I think the respondent will still have to go to the previous block to make changes.
@Tom_R and
@AndrewWKU I have done this before. My application was letting users edit their open-ends which the marketing team told them would be used in marketing materials. We wanted to give respondents a chance to edit their responses for grammar, etc. so they feel their voice is well represented publicly.
I ended up doing analysis on the second occurrence of the question only and leaving the first one out of the analysis.
You would repeat all of your questions you want to summarize/verify and set the default choice to equal what they said the first time around. These repeated fields are then editable but are storing what they already said. Qualtrics provides instructions on setting default choices - https://www.qualtrics.com/support/survey-platform/survey-module/question-options/add-default-choices/
In survey flow you can try showing the same block again and just add a text above as "Response Summary" so, even if the user changes the response it will get saved accordingly.
