How to add multiple users to a single Group?

What is the fastest way to add multiple (already signed up) users to a Group?

Currently when adding multiple users you can do the following in the Members section in the group:

  • Type in ‘user1’, hit enter, then type ‘user2’ then enter etc.

Is there a faster way to do this, like pasting in: user1,user2,user3 etc?

Ideally we could feed it a comma separated list. Currently that does not work.
