Survey Management in ARIS and ARCM

Hi,

I have a doubt and i hope that someone can help me.

I'm creating a survey in ARIS Architect. I modeled the authorization diagram as the image in attachment.

But i have a question. When we associate more than a user to a group in ARIS Architect , in ARIS Risk and Compliance Manager, the first user answering to the survey close that group. We really have to create a group for each user, in order to all users created answer to the survey?

Thanks
