pre-filling form fields from URL parameters

we send different email campaigns to different segments. i want to include a link to our form with some fields pre-filled based on the segment. like: form.tinycommand.com/our-form?source=email_campaign_q4&segment=enterprise and have the form automatically fill in hidden fields with those values so we know where the submission came from without asking the person is this possible? its a standard feature in most form builders but couldnt find docs on it here
