Support for Steam Groups/Tags?

[nokobon]

Is it possible to implement Steam groups/tags or adding users to a group so that they can appear in a different control channel? (Or is manual grouping already possible and I'm doing something wrong?)
I have a few friends tagged on Steam that I talk to often so that they appear separately from all of my other friends and I would like to do the same in bitlbee-steam

I tried manually grouping people by doing /join &channel, chan &channel set fill_by group, chan &channel set group groupname, and then /invite name &channel but I get a response of "<�root�>�� steam - Error: Failed to find any friend(s)"
Sending messages with name: message in &bitlbee works for sending to friends

Thanks
