Grouping contacts in Google Chat?

[Kelemvor]

We're switching to Google Apps at work and there doesn't seem to be any way to make groups of people in Google Chat. Does anyone know if any way to do that maybe from an add-on, extension, etc?

Just a simple grouping so I can expand a group to chat with someone from a certain team vs having everyone in a massive chat list and having to hunt through to find people.

I'm not real hopeful but maybe someone has a way.
