ADManager - Autologging into accounts to create Home Folders in File Redirection in Groups policy

We are a school and have hundreds of accounts we set up for exams a few times a year.

We have 2012 r2 group policy driven File Redirection set up so all users log in the first time and their home folder structure is created.

Unfortunately, this means logging into hundreds of these accounts to do the same for the exams (as we need to load files into the home folders for the students to use in exam conditions.

Is there any way of doing this automatically in ADManager Plus? I have looked at automation and I can create, enable, disable but nothing about logging in as a user.

Thanks in advance for you help
