Detecting checkbox untouched via sheetworkers

Often throughout my sheetworkers I check to see if a user has edited content before writing new content.
With text inputs and other similar inputs I can check if the field is empty or undefined.
However with checkboxes the value is either the value set on the checkbox or 0. I am unable to detect if the checkbox has never been touched like I am with text inputs as unedited (0) is the same value as checked and then unchecked (0).

Does anyone have a solution for this? Chris?

You could have a sheet worker set some other value when the checkbox changes, and check if that other value is set.

Just what I need, more fields on my sheet. :P
