This is what the respondent profiles are intended to be used for. To get a url, you'll want to make sure you access the member list from inside the capture (not the one that you can access from the left-hand side of the page). If you click the three dots next to a member entry, you can copy the URL to their profile by clicking on "Respondent Profile Link." You can also share them using the email template/scheduler features and inserting the variable %profile_url.
