Issue with Guacamole

[MARCO ANTONIO RIVERA ORTEGA]

Hello everyone, I have a question.
I have currently configured Guacamole to log in through Office 365. Every time 
someone enters the application, they do so and their new user is created, 
however I want to be able to upload a list of specific users.
Is there a way to add users in bulk? Perhaps through a .csv or .txt file and 
thus avoid the user having to log in to register for the first time in the 
application.
Is this possible?
