How do you invite more than one person at a time to a facebook group?

[Cadaverella]

Started a Facebook group, lots of my friends want to join but to send an invite I have to select everyone one at a time, cant bring up my whole friends list to select multiple people. I know you can share the groups but I would rather send personal invites to my friends and family. Any help would be much appreciated!
I don't see a 'find friends option?

click on find friends click on other tools select the categories you want, when u find the friends u want click add contact for all ur friend.

Try to update status at that time when your friends mostly come online in which you ask them or requesting them to join that group. Try this may be it helps.
