We use forms that allow for users to update their entries over time (with visibility of prior entries). Respondents to a survey can do this if there is an option to create and share an edit link after submission of a survey or simply to have a survey feature that allows for edit after submission via email collector (see survey monkey). This feature allows for several use cases - monitoring (e.g., weekly logs), journal research (i.e., tracking entries over time with visibility to previous entries), structured transition plans (i.e., entry and navigation within structured sections of a 'survey'/plan). Not sure if Voice has this option?
