Samsung Captivate :: Setting Up Groups For Texts

I did a search on this and found some posts on it but the wording was a bit different and there didn't seem to be any solutions.On my Captivate, I have all my contacts synced from my pc's google account. So when I click on Phone, Contacts, all my contacts have the google logo next to the phone number. When I click on Groups, it shows Family, Friends, Google, etc. It has zero contacts in all groups except for 30 contacts in my Google groups. (which is all the contacts I have in my phone.)On my friends Captivate, he doesn't have his contacts synced from Google. He goes into his Contacts, Groups and can click on Family or Friends and can add people from his contacts to the Family or Friends group. I can't do this cause all my contacts are synced from Google.Is there a work around for this? Hope I made sense to someone.
