I am creating a survey for the purpose of collecting data when biological samples are collected from roadkill or other dead wildlife in the field. Usually, the person collecting the sample will be alone and therefore will also fill out the form in Survey123. However, sometimes one person will collect the sample while another person will fill out the form. I would like to create a field called "Sampled by:" with a default value of the name of the survey user. Is this possible in Survey123?
