You can limit the targets that a survey can be performed on by using target groups.  First, create a target group to specify the targets that you want to use for this survey.  Next, follow the steps below to restrict your survey so that it can only be performed on targets in that group:

  1. Select your survey in the nav bar and go to the Survey Builder (Survey -> Edit Survey).
  2. Click the Restrictions button at the top of the Survey Builder.
  3. Use the Restrict to Target Group drop-down to choose the target group.
