You can easily create a new survey for an existing client from the Client & Form Settings page.
To reach it, get started on the main Admin Page.
Select a client, head to the Clients tab and use the Client & Form Settings link, or simply use the Quick Jump bar.
The top of the Client Administration page has a Survey section.
Look for a Create New Survey for Client_Name button below all the listed surveys.
A Survey Administration page will open, and the only required field to create a new survey is the Survey Name.
Scroll to the bottom of the page and use the Add New button.
