Copy wordpress user members to membership2

Hi Team

Sorry to say but this is poorly documented and I thought it would be simple. I have searched and searched the support forums to no avail so I am sorry to bother you.

I would like to bulk import selected users (these ones http://www.epuap.org/wp-admin/users.php?role=epuap_member) to a Memberships 2 member level, EPUAP Membership.

Is this possible or must they be done one at a time?

Thanks

Chris
