How to tell if any element on a form is changed

Hi, here is a nice little question. I have a form on a page that has about 20 elements in it. The text on the submit button says ‘Next’ therefore the form is automatically saved when the user clicks ‘Next’. The Success displays a notification message of a successful save as normal. All good so far.
But if the user has not made any changes and ‘Next’ is clicked, the notification message is still displayed.
So the question is, How to suppress the displaying of the notification message when no changes have been made. I know I could go to each element of the page and put something in the Change to flag that an edit has happened, but I am hoping Wappler has a status at Form level that can signify if any element has been changed? Anyone know?
