Add invited user automatically to group

Hallo,
Is it possible to add new invited user automatically to an existing group, so they can see more than one project?
I want to use the “Invite User” function to send emails to many addresses, and all users that create a account should automatically be member of one existing groun (eg: “new_user”).
Thanks

Short answer: No, or not that I’m aware of.

Hallo,
thanks for the answer!
