multiple ssh session broadcast groups

Hello.
I want to have multiple broadcast groups for ssh sessions, but it seems I can only create a single broadcast group?
To explain further, broadcast group allows me to group multiple SSH sessions so that I enter a command on one of them and that command get applied to all sessions at once.
I have two groups of sessions. The command I want to apply to first group need to be run only on sessions on that group.
I need second session's group to have its own broadcast group. in other words, when I apply a command to any session of second group, I need the command to be sent to only sessions part of second group without impacting first group.

Is this feature available? if not, would you please consider implementing it in the product?

Thank you.
