Maybe Peter Gousios and the team can comment on this?

I don't know how dynamic you are expecting things.  Pega survey isn't designed to be completely dynamic.  Depending on your goals visibiiltity conditions might get you a lot of the way there, but if your goal is completely dynamic survey's based on a pagelist, (IE have a separate question and set of answers), say to generate each question from an entry in the pagelist, then that will take a lot of customization,.  It is possible, to generate new question rules, and save them, but that again would take custom code, and be subject to changes if the internal rule structure that PegaSurvey implements changes in future releases.

I think you should discuss your business needs with your Account Executive, to see if this would be an enhancement that the PegaSurvey team might take up.

I would encourage you to review https://pdn.pega.com/documents/pegasurvey-63-sp1-user-guide to get a feel for the overall design of the PegaSurvey capabilities.

In my view, you would still need to create surveys from the survey builder.but then based on the each data instance(pagelist item) identify the survey name at the run time and display the survey in next screen(flow action).

you would need to run this in a loop(jump in flow) so that your survey is displayed for each page of pagelist.
