Possible to have changes NOT saved?

I want to create a chart that in editable, but defaults to the original numbers for every user. I want the user to be able to enter their own “projected values” and then save the output, but to not have that data saved, so the next user has the same default values. Is this possible?

I don’t see any technical limitations which can block the above scenario. The default component most probably will not have exactly the same functionality, though it can achieved by API
