Create phone contacts that you can customize and Link them to your google contacts. Both sets of values will appear in the combined contact.
For example, create a phone contact and put a ringtone. When you Link it to the google contact, only one contact will show and it will include both the google contact info as well as the custom ringtone.
Thanks, I did that for a few, but too tedious for all of them. Also, seems like it adds another step for voice recognition to misinterpret when voice dialing. There should be a way to bring them all over from Gmail to phone (we are living in the future you know). I am sure someone will figure it out..
