Buddy press: create groups from csv and import members from wp users

Hi to all,

for the first time i’ve installed buddypress with a wordpress installation.
It’s an impressive plugin/framework that do many things.
Now i have some questions…
There is a plugin for buddypress that gave the opportunity to create groups from an excel/csv file with the standard fields of buddypress? How can i do this?
Can I associate wordpress users with buddypress members and then point them to a specific group?

Thanks very much!
Gabriele
