A survey package can consist of one or more surveys. When a new survey is added to the package after a survey invitation has been already planned or sent, the new survey will not appear in planned or sent survey invitations. The new survey will only be added for survey invitations created after the change.
To be able to send the survey package with a new survey, it is advised to archive the existing survey invitations and send a new invitation using the updated survey package. For surveys that are already sent, it is possible to create an additional survey package and send this package separately.
