I wonder if you could work around this by adding a prefix to the names in your contact list such as G1- for group 1, G2- for group 2, etc. Then could you direct calls based on "G1*", "G2*, etc?For people and businesses that I want to keep in my contact list but don't want them to be mixed in with my main contact list, I add a lower case "z" to the front of their name. This forces them to the bottom of my contact list. They are still there but just out of the way.
