Hi Stephen, yes it is!  If the users are already in the system, you can go to People > select the user > Action> Send Pulse. 

If they are not yet in the system, or if there are a lot of new users, please reach out to Support@glintinc.com; we will can generate the missing questionnaires as long as the users are already added in the system. If they are not yet in the system, we need to have them loaded first and add to the survey distribution then generate missing questionnaire.
