Can I put Facebook contacts into groups with the GoContacts app?

[LynnNguyen]

I have the app GoContacts. I want to be able to group my Facebook contacts if that's possible. Also I can never group my other contacts all at once. When I check the ones that I want to group, it says "success" but some of them don't show up in the group and I have to go to their contact info and put them into the group manually.
