Facebook groups

[Deputy_sherriff]

I have a Facebook group, but it's been migrated to the new format.
Anyone who's wanted to stay in the group have stayed, but I want to invite more people to join.
I've just gone onto the group and the 'invite people to join' option has been replaced with 'add friends'. You can add everyone in your friends list, without the need to ask them first.
However, I would like to just add them all at the same time, as opposed to having to start typing a name and then adding them one by one. Does anyone know if/how I can do this?

Thanks :-)
