Show user's permission group's name in chat

Hello,

Is it possible to show an user's permission group's name in the chat as a prefix, similarly to what the i_group_show_name_in_tree does? For example, if I was in a group called Admin and would post a message to the chat, it would show up as:

[Admin] Rivenation: message

Thanks in advance!
