Yes. It was an initial requirement to support filling out both standard (US Government) and ad hoc (i.e. host nation specific) forms. In most cases, posts can easily configure Arrivals and Departures System (ADS) to automatically generate standard and ad hoc forms from employee profile data.
That is to say, an employee may never need to complete an updated SF-1190 or vehicle registration form. Rather, with the click of a button, the employee can generate a pre-filled form with basic bio data filled out including self, family member info, anything entered into ADS.
Ad hoc forms (i.e. host nation specific vehicle registration) can be imported into ADS and included for auto generation as long as they exist in original PDF format.
