Let's say you have someone who already filled out a screener with a scheduling question, but you decided to add new times since they filled out the screener. You can go to responses and check the box next to their name and then click Invite Selected to Be Scheduled.
This will not require them to answer any new questions on the screener except to pick a new time. They will receive an email asking them to pick a new time, and then will see a page like this:
Then you can invite them from Scheduling >> Calendar.
Now make sure to customize the "Invite Previous Respondent" under Scheduling >> Emails, because that's the email they will receive.
