Is it possible to change information after it has been entered?

Is it possible to change information after it has been entered? Example, I am using an appointment request on my Jotform. I am having that information sent to a Goolge Calendar and Google Spreadsheet.

However, I am trying to figure out if someone should call in and cancel that appointment, How can I delete it so that it is removed from Jotform, Google Calendar, and Google Sheets... Thus showing the time is now available again.

Hi Carr,

Please follow the instructions below: 

1. Click on Settings. Then click on the EMAIL on the left navigation bar.

2. Click on the edit icon for the Autoresponder.

3. Click on Form Fields and add the Edit Link option. Then save the changes.

In this way, users can update their form submission later.

The autoresponder mail is shown below:
