I agree, when you are sitting in an Alt Shot game and one of the other players has a friend that is green, it would be nice to reference them to the player you are inviting so they see where the invite is coming from.
This could all be solved with the WGT lobby that many of us have been asking for. I think that WGT is one of the very few online games that doesn't have some type of a lobby for it's players to use. It can't be that hard to set this up.
