Can I use a form I already created on Google Forms?
Yes. Go to Manage Projects, select your project, and click Workflow → Import form to link an existing Google Form. Then use Templates → Sync template to map the form questions to placeholders in your template.
Can I add images to form questions?
Yes. Doc Regia supports image questions and image answer options via the Google Forms REST API. You can add images directly from the form builder in the Questions tab when creating or editing a project.
