Hi there Yuan!
Thanks for booking with Pebble.
If you create an account before checking out, your answers will be saved and appear automatically in the questionnaire next time you make a booking to save you time.
This means you only need to click 1 button to submit if you are logged in and have already answered the same question before.
Of course, you still have the opportunity to edit the answer before submitting!
Please do let us know if you have any questions at all regarding this feature and we would be more than happy to help!
Kind regards,
Melissa from Pebble
