How to create groups using only numbers and not contacts

[ozzyPaulC]

Hi all,

I am coaching a team of 16 girls for the next 8 weeks, and need to send info to them now and again. So I thought I'd create a contact group. But I really don't want to add 16 new contacts to my phone. I was hoping i could create a group by just entering the 16 numbers straight into the new group.
But it seems I can only grab existing contacts. Does anyone know if this is possible?

Cheers,
