How can I use a validation to check if a file has been sabed before resetting only portions of a form?

I currently have two buttons on my form. One to clear the entire form and another to only clear certain fields. I have added a validation code to ask the user if they saved the form yet. However I have yet to find a way to skip the next action which is the built in "reset form". I have entered a similar validation on the other button but this is easily done since its purpose is to clear the entire thing. Any help would be great thanks!
