gravity-forms-multi-page-notifications

This is great! Keeps me updated when someone fills out all of the steps of my multi-step forms. The only reason I want this is because I want to make sure that my contacts are filling out all the of the steps instead of dropping off after step 3. Thank you for developing this! Suggestion: can we adjust the subject line based on the step. That way we know exactly which step with out viewing the entire email. Custom subject line?
